It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that Allah Almighty granted the Messenger of Allah (peace and blessings be upon him) the conquest of Khaybar. Then Aban bin Sa'id (may Allah be pleased with him) came to him (peace and blessings be upon him) with his troop, and asked for a share for himself and his companions. The Messenger of Allah (peace and blessings be upon him) did not give it. Abu Hurayrah (may Allah be pleased with him) said: The horses of these people were in poor condition.
