وَعَنْ أَبِي هُرَيْرَةَ رضى الله عنه
أَنَّ اَلنَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «اَلتَّثَاؤُبُ مِنْ اَلشَّيْطَانِ فَإِذَا تَثَاءَبَ أَحَدُكُمْ فَلْيَكْظِمْ مَا اِسْتَطَاعَ» رَوَاهُ مُسْلِمٌ 11 صحيح
The Prophet (sallallahu alayhi wa sallam) said: “Yawning is caused by the devil, so when one of you yawns he must repress it as much as he can.”.
