سنن أبي داود

Narrated Ali: The Messenger of Allah (ﷺ) said to me: Say: O Allah, guide me, and set me right. Remember by guidance (hidayah) the showing of the straight path, and remember by setting right (sadad) the setting right of an arrow. Then pointing to the middle finger and the one next to it, he said: He forbade me to wear a signet-ring on this finger of mine or on this (Asim was doubtful). He forbade me to wear qassiyyah (qasi garments) and mitharah. Abu Burdah said: We asked 'Ali: What is qasiyyah ? He said: These are garments imported to us from Syria or Egypt. They are stripped and marked like citrons. And mitharah was a thing made by women for their husbands.
