It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "My Ummah is an Ummah upon which mercy has been shown; the punishment has been lifted from them, except the punishment which they inflict on themselves with their own hands (upon one another)."
No one narrated this hadith from Sa'd bin Tariq (may Allah have mercy on him) except Sa'id bin Maslamah (may Allah have mercy on him).
