Brief Explanation
Benefits: … The hadith in which this supplication is specified with a mirror has been narrated by Ibn Sunni, but that narration is weak. Therefore, this supplication is established, but specifying it for any particular occasion is not established. However, it is a separate matter that upon seeing the beauty of one’s own creation, one should recite this supplication.
