Islamic Rulings on Shared Sleeping Spaces, Sibling Interaction, and Food from Mixed Income

وعليكم السلام ورحمة الله وبركاته

1. Sharing a Bed Due to Lack of Space

The Ruling:

It is not permissible for a father and his adult daughter (or a mother and her adult son) to sleep on the same bed, even if they are lying separately on different sides, and even if there is a genuine lack of space. This is because of the following evidence:

A. The Command to Separate Sleeping Spaces:

The Prophet ﷺ said:

«مُرُوا أَوْلَادَكُمْ بِالصَّلَاةِ وَهُمْ أَبْنَاءُ سَبْعِ سِنِينَ، وَاضْرِبُوهُمْ عَلَيْهَا وَهُمْ أَبْنَاءُ عَشْرٍ، وَفَرِّقُوا بَيْنَهُمْ فِي الْمَضَاجِعِ»

"Command your children to pray when they are seven years old, and beat them for it when they are ten, and separate them in their beds."

— [Sunan Abi Dawud 495, graded Hasan Sahih by Shaykh al-Albani]

If the Prophet ﷺ commanded separating children (who have not yet reached puberty) in their beds, then separating adults (who have reached puberty) is even more obligatory.

B. The Principle of Blocking the Means to Evil (سد الذرائع):

Shaykh al-Islam Ibn Taymiyyah (رحمه الله) stated:

"The Lawgiver blocks the means to evil even if the means itself is permissible, if it leads to what is forbidden."

— [Majmu' al-Fatawa, 15/100]

C. The Fatwa of the Permanent Committee:

The Permanent Committee for Islamic Research and Verdicts (al-Lajnah al-Da'imah) was asked about a father sleeping in the same bed as his adult daughter. They replied:

"It is not permissible for a man to sleep in one bed with his adult daughter or his sister or any other woman who is not his wife, because of the fitnah (temptation) and the means to evil that this involves."

— [Fatawa al-Lajnah al-Da'imah, 17/28]

D. What Should Be Done:

If there is genuinely no other sleeping arrangement available:

1. The father should sleep in a separate room or area — even on the floor, on a couch, or in another space.
2. If absolutely no separate space exists, then the father should sleep in a different area of the same room while the mother and daughter sleep together, or the father should sleep in a separate room entirely.
3. It is not permissible for the father to sleep on the same bed as his adult daughter under any circumstances.
4. The same applies to a mother and her adult son.

Shaykh Ibn 'Uthaymeen (رحمه الله) said:

"It is not permissible for a man to sleep in the same bed as his daughter who has reached puberty, or his sister, or his mother's sister, or any woman who is not his wife. This is a means to fitnah and is forbidden."

— [Fatawa Nur 'ala al-Darb, 12/345]

Summary: The father must find an alternative arrangement — even if it means sleeping on the floor, in a chair, or in another room. The daughter and mother may share a bed, but the father must be separate.

2. Spending Time with a Sibling

The Ruling:

It is permissible for a brother and sister to sit together and watch Islamic or educational content on a mobile phone, provided that:

1. There is no fear of fitnah (temptation) — this is the key condition.
2. There is no inappropriate intention from either party.
3. They observe proper hijab — the sister should be properly covered in front of her brother (though the brother is a mahram, the awrah of a woman in front of her mahram brother is the same as in front of other mahrams: the area between the navel and the knee, but it is better to be fully covered).
4. They do not lie together in a way that could lead to suspicion or temptation — sitting together is fine, but lying together on the same bed or in a compromising position should be avoided if there is any fear of fitnah.

Evidence:

Allah says:

وَقُل لِّلْمُؤْمِنَاتِ يَغْضُضْنَ مِنْ أَبْصَارِهِنَّ وَيَحْفَظْنَ فُرُوجَهُنَّ وَلَا يُبْدِينَ زِينَتَهُنَّ إِلَّا مَا ظَهَرَ مِنْهَا ۖ وَلْيَضْرِبْنَ بِخُمُرِهِنَّ عَلَىٰ جُيُوبِهِنَّ ۖ وَلَا يُبْدِينَ زِينَتَهُنَّ إِلَّا لِبُعُولَتِهِنَّ أَوْ آبَائِهِنَّ أَوْ آبَاءِ بُعُولَتِهِنَّ أَوْ أَبْنَائِهِنَّ أَوْ أَبْنَاءِ بُعُولَتِهِنَّ أَوْ إِخْوَانِهِنَّ أَوْ بَنِي إِخْوَانِهِنَّ أَوْ بَنِي أَخَوَاتِهِنَّ...

"And tell the believing women to lower their gaze and guard their chastity, and not to reveal their adornment except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons..."

— [Surah An-Nur 24:31]

This verse explicitly mentions that a woman may uncover in front of her brother, indicating that interaction with a mahram brother is permissible.

However, the Prophet ﷺ warned:

«الْحَلَالُ بَيِّنٌ وَالْحَرَامُ بَيِّنٌ، وَبَيْنَهُمَا مُشْتَبِهَاتٌ لَا يَعْلَمُهُنَّ كَثِيرٌ مِنَ النَّاسِ، فَمَنِ اتَّقَى الشُّبُهَاتِ فَقَدِ اسْتَبْرَأَ لِدِينِهِ وَعِرْضِهِ»

"The halal is clear and the haram is clear, and between them are doubtful matters that many people do not know. Whoever avoids the doubtful matters has protected his religion and his honor."

— [Sahih al-Bukhari 52, Sahih Muslim 1599]

Shaykh Ibn Baz (رحمه الله) said:

"It is permissible for a brother to sit with his sister and talk with her, provided there is no fear of fitnah and no inappropriate behavior. However, if there is any fear of fitnah, then it is not permissible."

— [Fatawa Ibn Baz, 20/345]

Shaykh al-Fawzan (حفظه الله) said:

"The basic principle is that interaction between mahrams is permissible, but if there is any fear of fitnah or the means to evil, then it becomes forbidden. The Muslim must be cautious."

— [Al-Muntaqa min Fatawa al-Fawzan, 3/245]

Summary: It is permissible for a brother and sister to sit together and watch Islamic content, provided there is no fear of fitnah and no inappropriate intention. However, lying together on the same bed should be avoided if there is any doubt.

3. Food and Gifts from a Relative Who Sells Cakes for Occasions

Understanding the Income:

Selling cakes for birthdays and wedding anniversaries involves:

1. Birthday cakes — celebrating birthdays is an innovation (bid'ah) that has no basis in Islam. The Prophet ﷺ said:

   «مَنْ أَحْدَثَ فِي أَمْرِنَا هَذَا مَا لَيْسَ مِنْهُ فَهُوَ رَدٌّ»

   "Whoever introduces into this affair of ours something that is not from it, it will be rejected."

   — [Sahih al-Bukhari 2697, Sahih Muslim 1718]

2. Wedding anniversary cakes — celebrating wedding anniversaries is also an innovation and imitation of the disbelievers. The Prophet ﷺ said:

   «مَنْ تَشَبَّهَ بِقَوْمٍ فَهُوَ مِنْهُمْ»

   "Whoever imitates a people is one of them."

   — [Sunan Abi Dawud 4031, graded Hasan Sahih by Shaykh al-Albani]

Therefore, the income from selling such cakes is haram or at least doubtful (shubhah) .

i) Eating Food Purchased with Haram Money as a Gift

The Ruling:

If the relative purchases food with money earned from selling haram cakes and brings it to your home as a gift:

• If the food itself is halal (e.g., rice, meat, fruit), and the only issue is the source of the money used to purchase it, then the majority of scholars hold that it is permissible to eat it, because the prohibition is connected to the means of acquisition, not the food itself.

Evidence:

Allah says:

فَكُلُوا مِمَّا رَزَقَكُمُ اللَّهُ حَلَالًا طَيِّبًا وَاشْكُرُوا نِعْمَتَ اللَّهِ إِن كُنتُمْ إِيَّاهُ تَعْبُدُونَ

"So eat of the lawful and good food which Allah has provided for you, and be grateful for the favor of Allah, if it is indeed He Whom you worship."

— [Surah An-Nahl 16:114]

Shaykh Ibn 'Uthaymeen (رحمه الله) was asked about eating food purchased with haram money. He replied:

"If the food itself is halal and the money used to buy it is haram, then the sin is on the one who earned the money, not on the one who eats the food. However, if the food was stolen or acquired through haram means directly, then it is not permissible to eat it."

— [Fatawa Nur 'ala al-Darb, 14/245]

Shaykh Ibn Baz (رحمه الله) said:

"If a person earns haram money and buys food with it, the food is halal for the one who eats it, but the one who earned the haram money is sinful. However, if the food itself is haram (e.g., pork, alcohol), then it is not permissible to eat it."

— [Fatawa Ibn Baz, 19/245]

However, if the food was purchased specifically with haram money and the relative is known to only deal in haram, then it is better to avoid it out of caution (wara'), especially if eating it would encourage them to continue in their haram trade.

Shaykh al-Fawzan (حفظه الله) said:

"If the food is halal and the money is haram, the food is permissible to eat, but it is better to avoid it if possible, especially if eating it would encourage the person to continue in haram."

— [Al-Muntaqa min Fatawa al-Fawzan, 4/125]

ii) Visiting Their Home and Eating Their Food When Their Income is Mixed

The Ruling:

If their income is mixed (some halal, some haram):

• It is permissible to visit them and eat their food, because:
  1. The food itself is halal.
  2. The haram income is mixed with halal income, and the majority of scholars hold that when halal and haram are mixed, the halal prevails if the haram is not the majority.
  3. Maintaining family ties (silat al-rahim) is obligatory.

Evidence:

Allah says:

وَاتَّقُوا اللَّهَ الَّذِي تَسَاءَلُونَ بِهِ وَالْأَرْحَامَ ۚ إِنَّ اللَّهَ كَانَ عَلَيْكُمْ رَقِيبًا

"And fear Allah through Whom you demand your mutual rights, and do not cut the relations of the wombs (kinship). Surely, Allah is Ever a Watcher over you."

— [Surah An-Nisa 4:1]

The Prophet ﷺ said:

«مَنْ أَحَبَّ أَنْ يُبْسَطَ لَهُ فِي رِزْقِهِ، وَيُنْسَأَ لَهُ فِي أَثَرِهِ، فَلْيَصِلْ رَحِمَهُ»

"Whoever wishes to have his provision expanded and his lifespan extended, let him maintain his ties of kinship."

— [Sahih al-Bukhari 5986, Sahih Muslim 2557]

Shaykh Ibn Baz (رحمه الله) said:

"If a person's income is mixed between halal and haram, it is permissible to eat from his food and to visit him, because the halal is mixed with the haram, and the basic principle is that the food is halal. However, if the haram is the majority or if the food itself is haram, then it is not permissible."

— [Fatawa Ibn Baz, 19/246]

Shaykh Ibn 'Uthaymeen (رحمه الله) said:

"If a person's income is mixed, the food is halal as long as the food itself is halal. The sin of the haram income is on the one who earned it. However, if you know that the food was purchased specifically with haram money and the person has no halal income, then it is better to avoid it."

— [Fatawa Nur 'ala al-Darb, 14/246]

iii) If They Invite You to Their Home for a Meal

The Appropriate Course of Action:

1. Accept the invitation — because maintaining family ties is obligatory, and the Prophet ﷺ encouraged accepting invitations.

   The Prophet ﷺ said:

   «لَوْ دُعِيتُ إِلَى كُرَاعٍ لَأَجَبْتُ، وَلَوْ أُهْدِيَ إِلَيَّ ذِرَاعٌ لَقَبِلْتُ»

   "If I were invited to a meal of a sheep's trotter, I would accept, and if a sheep's foreleg were given to me as a gift, I would accept it."

   — [Sahih al-Bukhari 2568]

2. Eat from the food — as long as the food itself is halal.

3. Advise them gently — if you have knowledge and they are open to advice, you may gently remind them that selling cakes for birthdays and anniversaries is not permissible, and that they should seek halal income.

   Allah says:

   وَذَكِّرْ فَإِنَّ الذِّكْرَىٰ تَنفَعُ الْمُؤْمِنِينَ

   "And remind, for indeed, the reminder benefits the believers."

   — [Surah Adh-Dhariyat 51:55]

4. Do not boycott them — cutting family ties is a major sin.

   The Prophet ﷺ said:

   «لَا يَدْخُلُ الْجَنَّةَ قَاطِعُ رَحِمٍ»

   "The one who severs family ties will not enter Paradise."

   — [Sahih al-Bukhari 5984, Sahih Muslim 2556]

5. If the food is known to be purchased exclusively with haram money and they have no halal income, then it is better to avoid eating and to advise them, but still maintain the visit and the family ties.

Shaykh al-Fawzan (حفظه الله) said:

"If a person is invited to a meal and the host's income is mixed, he should eat if the food is halal, and he should advise the host if possible. He should not boycott his family, because maintaining family ties is obligatory."

— [Al-Muntaqa min Fatawa al-Fawzan, 4/126]
