“✦ REVIVE A SUNNAH ⇨
“Covering the mouth with the right hand when YAWNING or suppressing it as much as one can” ✦
Narrated Abu Huraira Radi Allahu Anhu: The Prophet (Sallallahu Alaihi Wasallam) said, “Allah loves sneezing but dislikes yawning; so if anyone of you sneezes and then praises Allah, every Muslim who hears him (praising Allah) has to say Tashmit to him.
But as regards yawning, it is from Satan, so if one of you yawns, he should try his best to stop it, for when anyone of you yawns, Satan laughs at him.”
[Sahih Bukhair :: Vol. 8 :: Book 73 :: Hadith 245]”
