Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) narrates: So-and-so and I went to the Prophet (peace and blessings be upon him), and I said: O Messenger of Allah! You gave (wealth) to Banu al-Muttalib and left us out, although we and they are of one and the same standing in relation to you. The Prophet (peace and blessings be upon him) said: "Banu Hashim and Banu al-Muttalib are one and the same thing."
