Arabic (Original)
حَدَّثَنَا وَكِيعٌ حَدَّثَنَا سُفْيَانُ عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ عَنِ ابْنِ أَبِي سَعِيدٍ الْخُدْرِيِّ عَنْ أَبِيهِ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا تَثَاءَبَ أَحَدُكُمْ فَلْيَكْظِمْ مَا اسْتَطَاعَ فَإِنَّ الشَّيْطَانَ يَدْخُلُ فِي فِيهِ.
English Translation
Waki' told us: Sufyan told us, from Suhayl ibn Abi Salih, from the son of Abu Sa'id al-Khudri, from his father, who said: The Messenger of God (peace and blessings be upon him) said: "When one of you yawns, let him restrain it as much as he can, for Satan enters into his mouth."
