Is it permissible to utter the word "kufr" (disbelief) to avoid the destruction of one's wealth and honor, and is this considered duress (ikrah) that is recognized by Sharia?

According to the majority of scholars, the preservation of wealth is not considered a justifiable coercion for falling into disbelief. The proof for this is that Allah forbade believers from outwardly manifesting disbelief out of fear for their wealth and families, and He mandated emigration, not excusing those who lagged behind for the sake of their possessions.

Sheikh al-Islam mentioned that coercion into disbelief only occurs through torture, such as beating and shackling. The Hanafis and Malikis held the view that coercion into disbelief, or insulting the Prophet, peace be upon him, or slandering a Muslim, is only permissible out of fear of death or the loss of a limb, and that enduring death is superior.

This is supported by the story of Khubayb ibn Adi and the magicians of Pharaoh, and the hadith (definition) of Khabbab ibn al-Aratt, which demonstrates the great endurance of the Companions in the face of torment for the sake of their religion. Furthermore, the one who is compelled must strive to use tawriya (ambiguity) when uttering a word of disbelief.
