Allah's Wrath against the Apostate, except for the One Who is forced into Disbelief

Allah tells us that He is angry with them who willingly disbelieve in Him after clearly believing in Him, who open their hearts to disbelief finding peace in that, because they understood the faith yet they still turned away from it. They will suffer severe punishment in the Hereafter, because they preferred this life to the Hereafter, and they left the faith for the sake of this world and Allah did not guide their hearts and help them to stand firm in the true religion. He put a seal on their hearts so that they would not be able to understand what is beneficial for them, and He sealed their ears and eyes so that they would not benefit from them. Their faculties did not help them at all, so they are unaware of what is going to happen to them.

لاَ جَرَمَ

Commentary

From the first verse (106) comes the religious ruling about a person who has been compelled to utter a word of infidelity (kufr) under the threat that he would be killed if he did not do that. If he feels that, in all likelihood, the people threatening him have full capability of doing just that, then, this is a state of duress. If he were to utter some word of disbelief verbally - but, with a heart firm on Faith, a heart that shuns saying what is false and evil - then, there is no sin on him, nor will his wife become unlawful for him. (Qurtubi, Mazhari).
