Abu Kurayb narrated to us, [he said] Abu Usamah narrated to us, from Hisham ibn Urwah, from his father, who said: Nafi’ informed me, [he said]: I heard al-Abbas saying to al-Zubayr: "O Abu Abd Allah, here is where the Messenger of Allah, may Allah bless him and grant him peace, commanded you to plant the banner," meaning on the day of the conquest of Makkah.
