"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»
