Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّزَّاقِ قَالَ حَدَّثَنَا مَعْمَرٌ عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ عَنِ ابْنِ أَبِي سَعِيدٍ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا تَثَاءَبَ أَحَدُكُمْ فِي الصَّلَاةِ فَلْيَضَعْ يَدَهُ عَلَى فِيهِ فَإِنَّ الشَّيْطَانَ يَدْخُلُ مَعَ التَّثَاؤُبِ.

'Abd al-Razzaq told us, saying: Ma'mar told us, from Suhayl ibn Abi Salih, from Ibn Abi Sa'id, from Abu Sa'id al-Khudri, who said: The Prophet (peace and blessings be upon him) said, "When one of you yawns during prayer, let him place his hand over his mouth, for the devil enters with the yawn."
