“The Messenger of Allah ﷺ said: ‘When you call upon Allah, then do so with the palms of your hands (upwards). Do not do so with the back of your hands (upwards). And when you finish, then wipe your face with them.’”  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا دَعَوْتَ اللَّهَ فَادْعُ بِبَاطِنِ كَفَّيْكَ وَلاَ تَدْعُ بِظُهُورِهِمَا فَإِذَا فَرَغْتَ فَامْسَحْ بِهِمَا وَجْهَكَ
