He called the disbelievers to repent
allah possesses infinite mercy, compassion and forgiveness. in the qur'an, he reveals that he will accept the repentance of every one of his servants, and that he will forgive an individual's sins if he renounces them. the prophet (saas) related those tidings from allah to the disbelievers:
say to those who disbelieve that if they stop, they will be forgiven what is past; but if they return to it, they have the pattern of previous peoples in the past. (surat al-anfal: 38)
in the hadiths, the prophet (saas) told people that they can repent at any time:
"he who seeks repentance (from the lord ) before the rising of the sun from the west (before the day of resurrection), allah turns to him with mercy."60
so call and go straight as you have been ordered to. do not follow their whims and desires but say, 'i believe in a book sent down by allah sent down by allah and i am ordered to be just between you.
(surah ash-shura: 15)
