It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that when the Prophet (peace and blessings be upon him) returned from the Battle of Uhud, the women of the Ansar began to weep over their husbands who had been martyred. The Prophet (peace and blessings be upon him) said: "There is no one to weep for Hamza." So some women from the Ansar came and began to weep over Hamza (may Allah be pleased with him). Then the Prophet (peace and blessings be upon him) fell asleep, and when he woke up, those women were still weeping in the same way. The Prophet (peace and blessings be upon him) said: "Alas for them, are you still sitting here and weeping? Tell them to go back, and after today, do not weep over anyone who dies."
