[Machine] The Messenger of Allah ﷺ said, "If one of you yawns during his prayer or feels drowsy, he should turn away and perform ablution, then he should rebuild what has elapsed from his prayer as long as he did not speak." Ibn Juraij said, "If he speaks, he should start over." This narration has been narrated by a group from Isma'il bin 'Ayyash from Ibn Juraij from his father from the Prophet ﷺ in a mursal (disconnected) manner. And it has also been narrated by Ibn Juraij from Ibn Abi Mulaykah from Aisha in a mawsul (connected) manner.  

رَسُولَ اللهِ ﷺ قَالَ إِذَا قَاءَ أَحَدُكُمْ فِي صَلَاتِهِ أَوْ قَلَسَ فَلْيَنْصَرِفْ فَلْيَتَوَضَّأْ ثُمَّ لِيَبْنِ عَلَى مَا مَضَى مِنْ صَلَاتِهِ مَا لَمْ يَتَكَلَّمْ قَالَ ابْنُ جُرَيْجٍ فَإِنْ تَكَلَّمَ اسْتَأْنَفَ وَرَوَاهُ جِمَاعَةٌ عَنْ إِسْمَاعِيلَ بْنِ عَيَّاشٍ عَنِ ابْنِ جُرَيْجٍ عَنْ أَبِيهِ عَنِ النَّبِيِّ ﷺ مُرْسَلًا وَعَنْهُ عَنِ ابْنِ جُرَيْجٍ عَنِ ابْنِ أَبِي مُلَيْكَةَ عَنْ عَائِشَةَ مَوْصُولًا
