📖 Abu Huraira RadhiAllahu 'anhu narrated: Allah's noble Messenger Muhammad SallAllahu 'alaihi wa sallam said, "Verily, Allah likes sneezing and dislikes yawning. When one of you sneezes and praises Allah, it is a duty on every Muslim to say to him: 'May Allah have mercy on you.' As for yawning, it is from shaytan. When one of you yawns, let him hold it back (restrain the yawn) as much as he can. When one of you yawns, shaytan laughs at him."
