"There are three things that the Messenger of Allah ﷺ used to do and the people have abandoned; he used to raise his hands extended when praying, and he would fall silent briefly, and say takbir when he prostrated and when he sat up." (Using translation from Nasāʾī 883)
«ثَلَاثٌ كَانَ رَسُولُ اللهِ ﷺ يَعْمَلُ بِهِنَّ تَرَكَهُنَّ النَّاسُ كَانَ يَرْفَعُ يَدَيْهِ فِي الصَّلَاةِ مَدًّا وَيَسْكُتُ هُنَيَّةً وَيُكَبِّرُ إِذَا سَجَدَ وَإِذَا رَكَعَ»

جَاءَ أَبُو هُرَيْرَةَ إِلَى مَسْجِدِ بَنِي زُرَيْقٍ فَقَالَ ثَلاَثٌ كَانَ رَسُولُ اللَّهِ ﷺ يَعْمَلُ بِهِنَّ تَرَكَهُنَّ النَّاسُ كَانَ يَرْفَعُ يَدَيْهِ فِي الصَّلاَةِ مَدًّا وَيَسْكُتُ هُنَيْهَةً وَيُكَبِّرُ إِذَا سَجَدَ وَإِذَا رَفَعَ
