صحيح البخاري#6223Sahihحَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، حَدَّثَنَا سَعِيدٌ الْمَقْبُرِيُّ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم " إِنَّ اللَّهَ يُحِبُّ الْعُطَاسَ، وَيَكْرَهُ التَّثَاؤُبَ، فَإِذَا عَطَسَ فَحَمِدَ اللَّهَ، فَحَقٌّ عَلَى كُلِّ مُسْلِمٍ سَمِعَهُ أَنْ يُشَمِّتَهُ، وَأَمَّا التَّثَاوُبُ فَإِنَّمَا هُوَ مِنَ الشَّيْطَانِ، فَلْيَرُدَّهُ مَا اسْتَطَاعَ، فَإِذَا قَالَ هَا. ضَحِكَ مِنْهُ الشَّيْطَانُ ".
Narrated Abu Huraira:The Prophet (ﷺ) 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
