وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-قَالَ : { اَلتَّثَاؤُبُ مِنْ اَلشَّيْطَانِ فَإِذَا تَثَاءَبَ أَحَدُكُمْ فَلْيَكْظِمْ مَا اِسْتَطَاعَ } رَوَاهُ مُسْلِمٌ 1‏
Abu Hurairah (RA):

The Prophet (ﷺ) said: "Yawning is caused by the devil, so when one of you yawns he must repress it as much as he can." [Reported by Muslim].
