"The Messenger of Allah ﷺ did not raise his hands during any supplication except when praying for rain, when he used to raise his hands so high that the whiteness of his armpits could be seen." (Using translation from Nasāʾī 1513)   

«كَانَ رَسُولُ اللَّهِ ﷺ لَا يَرْفَعُ يَدَيْهِ فِي شَيْءٍ مِنَ الدُّعَاءِ إِلَّا فِي الِاسْتِسْقَاءِ»
