HADITH OF THE DAY
SNEEZING AND YAWNING
Narrated byAbu Huraira
The Prophet (Peace & Blessings of Allah upon Him) said, "Allah likes sneezing and dislikes yawning, so if someone sneezes and then praises Allah, then it is obligatory on every Muslim who heard him, to say: May Allah be merciful to you (Yar-hamuka-l-lah)."
"But as regards yawning, it is from Satan, so one must try one's best to stop it, if one says 'Ha' when yawning, Satan will laugh at him."
[Vol-8 Hadith-242 Sahih Al-Bukhari]
