A: It is permissible to profess Kufr if actually forced into it, while the heart of the coerced Muslim rests secure with firm faith, based on the general meaning of the Ayah saying:
Whoever disbelieved in Allâh after his belief, except him who is forced thereto and whose heart is at rest with Faith; but such as open their breasts to disbelief, on them is wrath from Allâh, and theirs will be a great torment.
