Musnad Abu Ya'la al-Mawsili 118:41

Muhammad ibn Abdullah ibn Numayr narrated to us, Rawh narrated to us, Usamah narrated to us, from Nafi’, from Ibn Umar, who said: And Usamah said: And al-Zuhri narrated to me, from Anas ibn Malik, who said: When the Messenger of Allah (may Allah bless him and grant him peace) returned from Uhud, he heard the women of the Ansar weeping. He said: "But Hamzah has no women to weep for him." That reached the women of the Ansar, so they wept for Hamzah. Then the Messenger of Allah (may Allah bless him and grant him peace) slept, then he woke up while they were still weeping. He said: "Woe to them! Are they still weeping since today? Let them weep, but let them not weep for any deceased person after today."
