The Messenger of Allaah (peace and blessings of Allaah be upon him) asked “ " Where is your Khutam chain mail?”»(Sunan abu Davud)
One of the companions of the Prophet (peace and blessings of Allaah be upon him) reports that after ‘Ali married Fatemah, he wanted to start a married life with her, but the Messenger of Allaah (peace and blessings of Allaah be upon him) told him not to do this until he gave her something as a marriage gift. 'Ali said," O Messenger of Allaah, but I have nothing! " And the Prophet (peace and blessings of Allaah be upon him) said, "Give her your coat of mail." And he gave her his chain mail, and then began a married life with her. A similar hadith is narrated from Ibn‘ Abbas.(Sunan abu Davud)
