What Quran Says About “Repentance”(Tawba)
Know they not that Allah doth accept repentance from His votaries and receives their gifts of charity, and that Allah is verily He, the Oft-Returning, Most Merciful? [9:104]
But those who reject Faith after they accepted it, and then go on adding to their defiance of Faith,- never will their repentance be accepted; for they are those who have (of set purpose) gone astray. [3:90]
Allah accept the repentance of those who do evil in ignorance and repent soon afterwards; to them will Allah turn in mercy: For Allah is full of knowledge and wisdom. [4:17]
He is the One that accepts repentance from His Servants and forgives sins: and He knows all that ye do. [42:25]
Of no effect is the repentance of those who continue to do evil, until death faces one of them, and he says, "Now have I repented indeed;" nor of those who die rejecting Faith: for them have We prepared a punishment most grievous. [4:18]
Never should a believer kill a believer; but (If it so happens) by mistake, (Compensation is due): If one (so) kills a believer, it is ordained that he should free a believing slave, and pay compensation to the deceased's family, unless they remit it freely. If the deceased belonged to a people at war with you, and he was a believer, the freeing of a believing slave (Is enough). If he belonged to a people with whom ye have treaty of Mutual alliance, compensation should be paid to his family, and a believing slave be freed. For those who find this beyond their means, (is prescribed) a fast for two months running: by way of repentance to Allah. for Allah hath all knowledge and all wisdom. [4:92]
Who forgiveth sin, accepteth repentance, is strict in punishment, and hath a long reach (in all things). there is no god but He: to Him is the final goal. [40:3]
O ye who believe! Turn to Allah with sincere repentance: In the hope that your Lord will remove from you your ills and admit you to Gardens beneath which Rivers flow,- the Day that Allah will not permit to be humiliated the Prophet and those who believe with him. Their Light will run forward before them and by their right hands, while they say, "Our Lord! Perfect our Light for us, and grant us Forgiveness: for Thou hast power over all things." [66:8]
