Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said concerning this statement of Allah Almighty: "Those who avoid the major sins and immoralities, except minor faults" [Surah al-Najm: 32]: That is, a man repents after committing an evil deed. The Messenger of Allah (peace and blessings be upon him) said: "O Allah, if You forgive, then forgive Your servants all their sins; and which servant of Yours is there from whom no sin occurs?"
