Many times, in the company of his followers, the Holy Prophet [Sallal Laahu Alaieh Wa Sallam] stated, "I can smell the beauty of my friend from the land of Yemen." This statement is in direct reference to the spiritual greatness of Hazrat Uwaies Qarani [Radiyal Laah Anhu].
Hazrat Umar [Radiyal Laahu Anhu] quotes Rasoolul Laah [Sallal Laahu Alaieh Wa Sallam] as saying, "Oh, Umar! From
Yemen a man will arrive whose name is Uwaies. He cares for his old and frail
mother. If for anything, he takes an oath in the name of Allaah [Ta’aalaa],
Allaah Kareem] will fulfill his oath. If you can ask from him prayers for your
own forgiveness, then you must do so."
