Musnad Abu Ya'la al-Mawsili 159:47

Bishr ibn Sayhan narrated to us, Halbas ibn Ghalib narrated to us, Sufyan al-Thawri narrated to us, from Abu al-Zinad, from al-A'raj, from Abu Hurayrah, who said: A man came to the Prophet, may Allah bless him and grant him peace, and said: "O Messenger of Allah, I have married off my daughter, and I would like for you to assist me with something." He said: "I have nothing, but when tomorrow comes, come to me with a wide-mouthed flask and a tree branch." And he mentioned the hadith in the *Fawa'id*.
