[Pooya/Ali Commentary 42:25] Whatever the sin, Allah's mercy is available to sincere repentance, at all times until the decree of condemnation is passed. He does not want to punish the offenders if they turn repentant to Him and live in the light of His guidance thereafter. In verse 53 of Zamur the Holy Prophet says: "Do not despair of the mercy of Allah. Verily Allah forgives all sins." Compared to what Islam offers to the sinners (repentance and their living an ordered life free from evil) the doctrine of unconditional redemption, just because a man, unjustly taken as the son of God, has given his blood, is incredible, because it gives unruly licence to sin which certainly spreads corruption, chaos and injustice. Jabir bin Abdullah Ansari relates an incident in which it is said that a man came into the masjid, prayed a two rak-at salat, and then said: "O Lord, I seek Your pardon." Imam Ali, who was there, said: "Your repentance is unacceptable. Tawbah (turning repentant unto ADah) should come together with a sincere determination to avoid sinning in the future." If any duty has been neglected it should be at once carried out. He who turns in repentance to Allah must feel sorry for the enjoyment of the sinful deed and humiliate himself before Allah for revolting against His command.
