“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
the Messenger of Allah (saas) said: "When you supplicate to Allah, supplicate with your palms uppermost, not with the backs of your hands uppermost, and when you finish, wipe your face with them."
قَالَ رَسُولُ اللَّهِ ﷺ إِذَا دَعَوْتَ اللَّهَ فَادْعُ بِبُطُونِ كَفَّيْكَ وَلاَ تَدْعُ بِظُهُورِهِمَا فَإِذَا فَرَغْتَ فَامْسَحْ بِهِمَا وَجْهَكَ
“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.’” (Using translation from Ibn Mājah 1181)
"إِذا دَعَوتَ الله فادع اللهَ ببطنِ كفيكَ، ولا تدعُ بظُهورِهما، فإِذا فرغت فامْسَحْ بهما وَجْهَكَ" .
