Answer (Hanafi Fiqh)

Wa ʿalaykum al-salām wa raḥmatullāh wa barakātuh.

Short answer

No — you are not a kāfir or mushrik. Your repentance (tawbah) is valid, and the mere act of having followed a page, or even a doubtful reaction to a post, does not constitute kufr or shirk in itself. Kufr and shirk are matters of belief (iʿtiqād) and deliberate affirmation/approval of the content of kufr — not of incidental clicks, follows, or forgotten reactions. Since you have repented and disavowed the ideology, you remain a Muslim, in shā’ Allāh.

Detailed ruling

1. The principle: kufr requires intent and belief, not mere action of the limb

The foundational Hanafi principle is stated in Radd al-Muḥtār (Ibn ʿĀbidīn, 4/224, Bāb al-Murtadd) and al-Baḥr al-Rāʾiq:

«الْكُفْرُ يَتَعَلَّقُ بِالِاعْتِقَادِ وَالْقَوْلِ، لَا بِمُجَرَّدِ الْفِعْلِ»

“Kufr attaches to belief and speech, not to mere physical action.”

And in Fatāwā ʿĀlamgīrī (2/258, Kitāb al-Murtadd):

«لَا يَكْفُرُ الْمُسْلِمُ بِالشَّكِّ وَلَا بِالْفِعْلِ الَّذِي لَمْ يَقْتَرِنْ بِهِ اعْتِقَادُ الْكُفْرِ»

“A Muslim does not become a kāfir by doubt, nor by an action unaccompanied by belief in kufr.”

Following a page, or a reaction (like/comment) that you are not even certain you made, and which you did not intend as approval of shirk/kufr, does not remove you from Islam.

2. The ḥadīth on the man who found a people worshipping idols

The Prophet ﷺ said about the one who intends to do a good deed but does not do it — it is written as a good deed; and about the one who intends a sin but does not do it — it is written as a good deed, because he left it for Allah (Ṣaḥīḥ al-Bukhārī 6491, Ṣaḥīḥ Muslim 131). This shows that the intention and belief are what count before Allah, not incidental or forgotten acts.

3. The ruling on following/“liking” a page of kufr

• If a person deliberately follows or endorses a page of shirk/kufr out of belief in it, that is kufr — and he must renew his īmān and tawbah.
• If he did so without believing in it — out of curiosity, accident, or before realizing — then it is a sin (if deliberate) but not kufr. It is wiped out by sincere tawbah.

Ibn ʿĀbidīn (Radd al-Muḥtār, 4/225) and Mullā ʿAlī al-Qārī (Sharḥ al-Fiqh al-Akbar, p. 178) both emphasize that a Muslim is not declared kāfir except by explicit denial or affirmation of kufr, and that doubt (shakk) does not make one kāfir.

4. Your specific situation

• You repented — tawbah is accepted, and Allah says: “Say: O My servants who have transgressed against themselves, do not despair of the mercy of Allah. Indeed, Allah forgives all sins.” (al-Zumar 39:53)
• You cannot access the fake account to delete/unlike — this is beyond your control (lā ḥawla wa lā quwwata illā billāh). The Sharīʿah does not burden a soul beyond its capacity (al-Baqarah 2:286). You are not accountable for what you cannot undo.
• You doubt whether you reacted — a doubt (shakk) about whether a sin occurred does not establish the sin, let alone kufr. The principle: “al-yaqīn lā yazūlu bi-l-shakk” — certainty is not removed by doubt.
• You deleted your main account out of taqwā — this is a sign of sincere repentance and is praiseworthy.

5. What you should do now

1. Renew your īmān as a precaution and act of humility (not because you are kāfir): recite the Kalimah and make tawbah. This is the advice of the fuqahāʾ for anyone who fears having fallen into kufr — see Fatāwā ʿUthmānī (1/120) and Imdād al-Fatāwā (4/380).
2. Make istighfār for the fake ID and for any doubtful reaction.
3. Do not obsess over waswās (Satanic whispers). The Prophet ﷺ warned against waswās in īmān (Ṣaḥīḥ Muslim 132) and said: “He who repents of a sin is like one who has no sin.” (Sunan Ibn Mājah 4252, ḥasan).
4. Give ṣadaqah and increase good deeds, as tawbah is completed by good works (Maʿārif al-Qurʾān, Sūrah al-Tawbah).
5. If you ever regain access, unfollow/unlike then — but its absence now is not a sin upon you.

6. A caution

Do not declare yourself kāfir or mushrik. The Prophet ﷺ said: “Whoever says to his brother, ‘O kāfir,’ and it is not so, it returns upon him.” (Ṣaḥīḥ al-Bukhārī 6104). Fearing kufr out of scrupulousness is good, but self-declaring kufr is itself a grave error. You are a Muslim; repent and move on.

Conclusion

You are not a kāfir or mushrik. Your tawbah is valid. Following a page or a doubtful reaction without belief in its kufr does not expel you from Islam. What you cannot undo is excused. Renew your īmān as a precaution, make istighfār, and do not let Shayṭān trap you in waswās. And Allah knows best.
