Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "When a servant remains sitting at his place of prayer after the prayer, the angels keep supplicating for mercy for him, and the angels' supplication for him is: 'O Allah, forgive him.' And if a man is sitting waiting for the prayer, the angels supplicate for mercy for him, and their supplication for that person is: 'O Allah, forgive him; O Allah, have mercy on him.'"
Imam Ahmad recorded it; its chain contains a narrator, Ata' bin al-Sa'ib, who is thiqah (trustworthy), but he suffered from confusion (ikhtilat) in the last part of his life.
