فَإِن زَلَلْتُم مِّن بَعْدِ مَا جَاءَتْكُمُ الْبَيِّنَاتُ فَاعْلَمُوا أَنَّ اللَّهَ عَزِيزٌ حَكِيمٌ
And should you stumble after the manifest proofs that have come to you, know that Allah is all-mighty, all-wise.
Agha Ali Puya Commentary
Commentary on Quran 2:209
[Pooya/Ali Commentary 2:209] Those who made a show of becoming Muslims to save their private interests will certainly backslide, but their defection shall not affect the cause of Allah in any way, nor cause any inconvenience to those who believe in Allah. Those who go astray shall be the losers.
