Hadith 8232
عَنِ ابْنِ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا تَثَاءَبَ أَحَدُكُمْ فَلْيَكْظِمْ مَا اسْتَطَاعَ فَإِنَّ الشَّيْطَانَ يَدْخُلُ فِي فِيهِ
Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: When any of you yawns, he should restrain it as much as possible, because the devil enters the mouth.
Hadith 8233
وَعَنْهُ أَيْضًا عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا تَثَاءَبَ أَحَدُكُمْ فِي الصَّلَاةِ فَلْيَضَعْ يَدَهُ عَلَى فِيهِ فَإِنَّ الشَّيْطَانَ يَدْخُلُ مَعَ التَّثَاؤُبِ
Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) also narrates that the Noble Prophet (peace and blessings be upon him) said: When any of you yawns during prayer, he should place his hand over his mouth, because Satan enters the mouth along with the yawn.
Hadith 8234
عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِنَّ اللَّهَ عَزَّ وَجَلَّ يُحِبُّ الْعُطَاسَ وَيَكْرَهُ التَّثَاؤُبَ فَمَنْ عَطَسَ فَحَمِدَ اللَّهَ فَحَقٌّ عَلَى مَنْ سَمِعَهُ أَنْ يَقُولَ يَرْحَمُكَ اللَّهُ وَإِذَا تَثَاءَبَ أَحَدُكُمْ فَلْيَرُدَّهُ مَا اسْتَطَاعَ وَلَا يَقُلْ آهْ آهْ فَإِنَّ أَحَدَكُمْ إِذَا فَتَحَ فَاهُ فَإِنَّ الشَّيْطَانَ يَضْحَكُ مِنْهُ أَوْ بِهِ قَالَ حَجَّاجٌ رَضِيَ اللَّهُ عَنْهُ فِي حَدِيثِهِ وَأَمَّا التَّثَاؤُبُ فَإِنَّمَا هُوَ مِنَ الشَّيْطَانِ
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Indeed, Allah Almighty likes sneezing and dislikes yawning. When a person sneezes and says "Alhamdulillah," it is the right of the one who hears him to say "Yarhamukallah." And when any one of you yawns, he should try his best to restrain it and not make the sound "aah," because when any one of you opens his mouth, Satan laughs at him. In the narration of Hajjaj, it is mentioned: As for yawning, it is from Satan.
Hadith 8235
وَعَنْهُ أَيْضًا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ إِنَّ التَّثَاؤُبَ مِنَ الشَّيْطَانِ فَإِذَا تَثَاءَبَ أَحَدُكُمْ فَلْيَكْظِمْ مَا اسْتَطَاعَ
It is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Yawning is from the devil, so when any of you feels like yawning, he should restrain it as much as possible.
