"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." (Using translation from Nasāʾī 1144)
كَانَ رَسُولُ اللهِ ﷺ «إِذَا افْتَتَحَ الصَّلَاةَ كَبَّرَ وَرَفَعَ يَدَيْهِ وَإِذَا رَكَعَ وَبَعْدَ الرُّكُوعِ وَلَا يَرْفَعُ 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
"The Messenger of Allah ﷺ used to raise his hands when he started to pray, and when he bowed, and when he stood up, but he did not do that when he prostrated."
كَانَ رَسُولُ اللَّهِ ﷺ يَرْفَعُ يَدَيْهِ إِذَا افْتَتَحَ الصَّلاَةَ وَإِذَا رَكَعَ وَإِذَا رَفَعَ وَكَانَ لاَ يَفْعَلُ ذَلِكَ فِي السُّجُودِ
“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 النَّبِىَّ ﷺ إِذَا افْتَتَحَ الصَّلاَةَ رَفَعَ يَدَيْهِ حَتَّى تُحَاذِىَ مَنْكبيْهِ، وَإذَا رَكَعَ، وَبَعْدَ مَا يَرفَعُ وَلاَ يَرْفَعُ يَدَيْهِ بَيْنَ السَّجْدَتَيْن".
