Hadith 2243
وَفِي رِوَايَةِ ابْنِ عَبَّاسٍ قَالَ: «سَلُوا اللَّهَ بِبُطُونِ أَكُفِّكُمْ وَلَا تَسْأَلُوهُ بِظُهُورِهَا فَإِذَا فَرَغْتُمْ فامسحوا بهَا وُجُوهكُم» . رَوَاهُ دَاوُد
In the version of Ibn ‘Abbas he said, “When you make requests of God, do so with the palms of your hands and not the backs upward, and when you are finished wipe your faces with them.” Abu Dawud transmitted it.
