Hadith 585
Sayyiduna Anas bin Malik, may Allah be pleased with him, says: The Banu Rabi’ah came to the Messenger of Allah, peace and blessings be upon him, seeking permission to set out with the army before others. Then Jibril, peace be upon him, came to the Prophet and said: “O Muhammad! Allah, the Exalted, sends peace upon you and commands you to tell Banu Rabi’ah not to set out with the army first, otherwise I will diminish your friends.”
