Sunnan Abu Dawud Collection: ::Book Number 11:: Hadith # 2121
Narrated A man from the Companion of the Prophet: Muhammad ibn AbdurRahman ibn Thawban reported on the authority of a man from the Companions of the Prophet (peace_be_upon_him): When Ali married Fatimah, daughter of the Apostle of Allah (peace_be_upon_him), he intended to have intercourse with her. The Apostle of Allah (peace_be_upon_him) prohibited him to do so until he gave her something. Ali said: I have nothing with me, Apostle of Allah. The Prophet (peace_be_upon_him) said: Give her your coat of mail. So he gave her his coat of mail, and then cohabited with her.
