Sunan an-Nasa'i 881
It was narrated from Malik bin Al-Huwairith said:
"I saw the Messenger of Allah (ﷺ), when he started to pray, raise his hands, and when he bowed, and when he raised his head from bowing, until they were parallel with the top of his ears."
أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا ابْنُ عُلَيَّةَ، عَنِ ابْنِ أَبِي عَرُوبَةَ، عَنْ قَتَادَةَ، عَنْ نَصْرِ بْنِ عَاصِمٍ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم حِينَ دَخَلَ فِي الصَّلاَةِ رَفَعَ يَدَيْهِ وَحِينَ رَكَعَ وَحِينَ رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ حَتَّى حَاذَتَا فُرُوعَ أُذُنَيْهِ ‏.‏
