Raising the hands when rising from the first prostration
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ نَصْرِ بْنِ عَاصِمٍ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا دَخَلَ فِي الصَّلاَةِ رَفَعَ يَدَيْهِ وَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ فَعَلَ مِثْلَ ذَلِكَ كُلَّهُ يَعْنِي رَفْعَ يَدَيْهِ .
It was narrated from Malik bin Al-Huwairith that: When the Prophet (ﷺ) of Allah (ﷺ) started to pray, he raised his hands, and when he bowed, he did likewise, and when he raised his head from bowing he did likewise, and when he raised his head from prostration, he did likewise, meaning he raised his hands.
