Sayyiduna al-Nu'man bin Bashir (may Allah be pleased with him) says concerning the verse, "And do not throw yourselves with your own hands into destruction" [Surah al-Baqarah: 195]: When a person commits a sin, let him not throw himself into destruction, and let him never say that there is no forgiveness for him; rather, he should seek forgiveness and turn to Allah. Allah Almighty is Forgiving, Merciful.
