I saw the Messenger of Allah ﷺ raising his hands apposite the shoulders at the time of beginning the prayer and before bowing down and after coming back to the position after bowing. but he did not raise them between two prostrations.

رَأَيْتُ رَسُولَ اللَّهِ ﷺ إِذَا افْتَتَحَ الصَّلاَةَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ مَنْكِبَيْهِ وَقَبْلَ أَنْ يَرْكَعَ وَإِذَا رَفَعَ مِنَ الرُّكُوعِ وَلاَ يَرْفَعُهُمَا بَيْنَ السَّجْدَتَيْنِ

"When the Prophet ﷺ started to pray he said the takbir and raised his hands, and when he bowed, and after bowing, but he did not raise them between the two prostrations."

كَانَ النَّبِيُّ ﷺ إِذَا افْتَتَحَ الصَّلاَةَ كَبَّرَ وَرَفَعَ يَدَيْهِ وَإِذَا رَكَعَ وَبَعْدَ الرُّكُوعِ وَلاَ يَرْفَعُ بَيْنَ السَّجْدَتَيْنِ

His father said: "I saw the Messenger of Allah ﷺ when he started to pray, raise his hands until they were parallel to his shoulders, (and he did that) when he bowed and when he raised his head from bowing."

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

his father (Ibn Umar) who said: "I saw Messenger of Allah when he opened the Salat, raising his hands to the level of his shoulders, and (again) when he bowed, and when he raised his head from bowing." In his narration, Ibn Abi Umar added: "And he wuld not raise them between the two prostrations."

رَأَيْتُ رَسُولَ اللَّهِ ﷺ إِذَا افْتَتَحَ الصَّلاَةَ يَرْفَعُ يَدَيْهِ حَتَّى يُحَاذِيَ مَنْكِبَيْهِ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَزَادَ ابْنُ أَبِي عُمَرَ فِي حَدِيثِهِ وَكَانَ لاَ يَرْفَعُ بَيْنَ السَّجْدَتَيْنِ

“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

«رَأَيْتُ النَّبِيَّ ﷺ إِذَا افْتَتَحَ الصَّلَاةَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا مَنْكِبَيْهِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ وَبَعْدَ مَا يَرْفَعُ رَأْسَهُ مِنَ الرُّكُوعِ وَلَا يَرْفَعُ بَيْنَ السَّجْدَتَيْنِ»

His father said: "I saw the Messenger of Allah ﷺ when he started to pray, raise his hands until they were parallel to his shoulders, (and he did that) when he bowed and when he raised his head from bowing." (Using translation from Nasāʾī 1025)

رَأَيْتُ رَسُولَ اللهِ ﷺ «إِذَا افْتَتَحَ الصَّلَاةَ يَرْفَعُ يَدَيْهِ حَتَّى يُحَاذِي مَنْكِبَيْهِ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ»

[Machine] I saw the Messenger of Allah ﷺ when he started the prayer, he raised his hands until they aligned with his shoulders. And when he wanted to bow, and after he raised from bowing, he did not raise between the two prostrations.

رَأَيْتُ رَسُولَ اللهِ ﷺ إِذَا افْتَتَحَ الصَّلَاةَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ مَنْكِبَيْهِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ وَبَعْدَمَا يَرْفَعُ مِنَ الرُّكُوعِ وَلَا يَرْفَعُ بَيْنَ السَّجْدَتَيْنِ
