Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) took the banner, waved it and then said: Who will take it with its due right? Sayyiduna al-Zubayr (may Allah be pleased with him) came and said: I will. The Prophet (peace and blessings be upon him) said: Step back. Then another man came and said: I will. The Prophet (peace and blessings be upon him) said: Step back. Then another man stood up and said: I will. The Prophet (peace and blessings be upon him) said: Step back. Then the Prophet (peace and blessings be upon him) said: By the One who has honoured Muhammad, I will give this banner to a man who will not flee. Ali, come forward! Sayyiduna Ali (may Allah be pleased with him) took the banner and then set off, until Allah Almighty granted him the conquest of Fadak and Khaybar, and he brought back their ajwah dates and dried meat (qadid).
Abu Ya'la recorded it, and its narrators are the narrators of the Sahih, except Abdullah bin Ismah, who is thiqah (trustworthy) but makes mistakes.
