First you were a believer...
First you were a believer, the Prophet chose you as a brother, your selflessness shone out on the night of the Prophet's escape from Mecca (laylatu 'l-mabit) when you slept in the place of the Prophet in his bed, you put yourself forward as a lure for swords. Truly your service for Islam cannot be denied.
But God also said to His Prophet: `If you associate (others with God) your work will come to naught.' Now that you have become a disbeliever you have cancelled out your past deeds." What could `Ali do, faced with this, with this man's voice shouting out the Qur'an? He remained silent until the man reached the end of the verse; and when he finished, 'Ali continued with the prayer. Then Ibn al-Kawwa' repeated the verse, and meanwhile `Ali fell silent again.
`Ali's behavior with them was also just as we noted before, namely, he never caused them any trouble, not even cutting off their wages from the treasury ( baitu 'l-mal ). However, as they began to despair of 'Ali ever repenting, their activities gradually changed.
