He saw the Prophet ﷺ raise his hands when he bowed, and when he raised his head from bowing, until they were in level with the highest part of his ears.  

أَنَّهُ رَأَى رَسُولَ اللَّهِ ﷺ يَرْفَعُ يَدَيْهِ إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ 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.  

أَنَّهُ رَأَى النَّبِيَّ ﷺ رَفَعَ يَدَيْهِ فِي صَلاَتِهِ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا سَجَدَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ حَتَّى يُحَاذِيَ بِهِمَا فُرُوعَ أُذُنَيْهِ  

“I saw the Messenger of Allah ﷺ raising his hands until they were parallel to his shoulders when he started the prayer, and when he bowed in Ruku’, and when he raised his head from Ruku’, but he did not raise them between the two prostrations.”  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ إِذَا افْتَتَحَ الصَّلاَةَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا مَنْكِبَيْهِ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَلاَ يَرْفَعُ بَيْنَ السَّجْدَتَيْنِ  

He saw the Prophet ﷺ raise his hands when he bowed, and when he raised his head from bowing, until they were in level with the highest part of his ears. (Using translation from Nasāʾī 1056)   

أَنَّهُ رَأَى رَسُولَ اللهِ ﷺ يَرْفَعُ يَدَيْهِ إِذَا أَرَادَ أَنْ يَرْكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ حَتَّى يُحَاذِيَ بِهِمَا فُرُوعَ أُذُنَيْهِ  

"رَأَيْتُ النَّبِىَّ ﷺ رَفَعَ يَدَيْه إِذَا رَكَعَ، وَإِذَا رَفَعَ رَأسَهُ مِنَ الركُوعِ حَتَّى يُحَاذِى بِهِمَا فُرُوعَ أُذُنَيْهِ".
