Al-Hakam bin Mina' states: The Prophet (peace and blessings be upon him) said to Sayyiduna Umar (may Allah be pleased with him): Gather for me the people of Quraysh who are here. Sayyiduna Umar (may Allah be pleased with him) gathered them, and then he said: O Messenger of Allah! Will you go out to them, or should they come in? The Prophet (peace and blessings be upon him) said: Rather, I will go out to them. Then he came out and said: O people of Quraysh! Is there anyone among you who is not one of you? They replied: No, except our nephew (a sister's son). The Prophet (peace and blessings be upon him) said: The sister's son of a people is one of them. Then the Prophet (peace and blessings be upon him) said: "O people of Quraysh! Know that the closest of people to the Prophet are the pious. So consider carefully, lest on the Day of Resurrection people come with deeds and you come with the world, carrying it, and I turn my face away from you." Then the Prophet (peace and blessings be upon him) recited this verse: "Indeed, the closest of people to Ibrahim are those who followed him, and this Prophet, and those who believe; and Allah Almighty is the Protector of the believers."
Abu Ya'la recorded it as a mursal narration; its chain contains a narrator, Abu al-Huwayrith, whom Ibn Hibban and others declared thiqah (trustworthy), and more than one declared him da'if (weak); the rest of its narrators are the narrators of the Sahih.
