“If ye (but) eschew the most heinous of the things which ye are forbidden to do, We shall expel out of you all evil in you, and admit you to a Gate of great honor.” [The Holy Quran: Nisaa 4:31] Then they asked him: “Who then does intercession apply to?” Imam Kazim (a.s) said: “My father quoted on the authority of his grandfather who had quoted on the authority of Imam Ali (a.s): “I heard God's Prophet (a.s) say: “My intercession applies to those of my people who have committed major sins, but good people do not need any intercession.” Muhammad ibn Abi Ommer asked Imam Kazim (a.s): “O' Grandson of the Prophet! How does intercession apply to those who have committed major sins even though the Almighty God said: “And they offer no intercession except for those who are acceptable and they stand in awe and reverence of His (glory).”[The Holy Quran: Anbiyaa 21:28] and whoever commits a major sin is not acceptable?” Imam Kazim (a.s) said: “O' Abu Ahmad! Any believer who commits a sin will become sorry, and God's Prophet (a.s) said being sorry itself is a form of repentance. He also said: “Whoever is pleased with his good deeds and is unhappy with his bad deeds is a believer. Whoever is not sorry about his sins is not a believer. There will be no intercession for him since he is an oppressor. God the Almighty said: “No intimate friend nor intercessor will the wrong-doers have, who could be listened to.”[The Holy Quran: Mu-min 40:18] Then he asked: “O' grandson of the Prophet! How can someone who does not repent for committing a sin be not considered a believer?” Imam Kazim (a.s) said: “O' Abu Ahmad! There is no one that knows if he commits a major crime he will be punished, and does not feel sorry when he commits it. Once he feels sorry, this is considered to be repentance, and thus he deserves intercession. But if he does not become sorry, he is considered to be one who insists on committing sins. Such a person will never be forgiven since as a result of the sins that he has committed, he is no longer a believer. If he believed in the punishment he would have repented. God's Prophet (a.s) said: “Major sins are eliminated by repentance, and minor sins turn into major sins by insisting on committing sins.” God the Almighty said: “And they offer no intercession except for those who are acceptable.”[The Holy Quran: Anbyaa 21:28] They will not intercede on behalf of those whose religion is not accepted by God. Religion consists of confessing to recompense for good and bad deeds. Whoever has a religion that is accepted by God will be sorry for committing sins since he is aware of the punishment in the Hereafter.”
