Narrated Abu Burdah bin Abi Musa:from his father, that the Messenger of Allah (ﷺ) said: "Allah sent down two guarantees of safety for the benefit of my Ummah: And Allah would not punish them while you are among them, nor will He punish them while they seek forgiveness (8:33). So when I pass, I leave seeking forgiveness among them until the Day of Resurrection
