Narrated in Sahih Muslim, Syarh an-Nawawi, 1 hadith from Anas ibn Malik r.a he said, "Verily Prophet pbuh in the time of asking for rain, he made the back side of his hand facing towards sky" - turning hand up-side down while praying for removal of disaster is the practice of Prophet pbuh

"Diriwayatkan dalam Sahih Muslim, Syarh an-Nawawi, sebuah hadis dr Anas bin Malik r.a katanya: ''Sesungguhnya Nabi s.a.w ketika memohon hujan, maka baginda s.a.w menjadikan belakang tapak tangannya ke langit." - membalikkan tapak tangan ketika berdoa menolak bala adalah amalan Baginda s.a.w. =)
