The Book of The At-Tatbiq (Clasping One's Hands Together) — Hadith #1087
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ شُعْبَةَ، عَنْ قَتَادَةَ، عَنْ نَصْرِ بْنِ عَاصِمٍ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، أَنَّهُ رَأَى النَّبِيَّ صلى الله عليه وسلم رَفَعَ يَدَيْهِ فِي صَلاَتِهِ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا سَجَدَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ حَتَّى يُحَاذِيَ بِهِمَا فُرُوعَ أُذُنَيْهِ .
He saw the Prophet (ﷺ) raise his hands when praying, when he bowed, when he raised his head from bowing, when he prostrated and when he raised his head from prostrating, until they were in level with the top part of his ears.
