Musannaf Ibn Abi Shayba 36:87

Yazid ibn Harun narrated to us, from Hammad ibn Salamah, from Hisham ibn Urwah, from his father, that when the Messenger of Allah (may Allah bless him and grant him peace) migrated to Medina, he, Abu Bakr, and Amir ibn Fuhayrah were met on the road by a gift from Talhah to Abu Bakr, which contained white garments. The Messenger of Allah (may Allah bless him and grant him peace) and Abu Bakr entered Medina wearing them.
