"Shall I not tell you about the prayer of the Messenger of Allah ﷺ? He stood and raised his hands the first time and then he did not do that again." (Using translation from Nasāʾī 1026)
أَلَا أُخْبِرُكُمْ بِصَلَاةِ رَسُولِ اللهِ ﷺ قَالَ «فَقَامَ فَرَفَعَ يَدَيْهِ أَوَّلَ مَرَّةٍ ثُمَّ لَمْ يَرْفَعْ»
