Prayer (Kitab Al-Salat): Detailed Injunctions about Witr
Regarding Supplication (Ad-Du'a)
حَدَّثَنَا عَمْرُو بْنُ عُثْمَانَ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنِي عَبَّاسُ بْنُ عَبْدِ اللَّهِ بْنِ مَعْبَدِ بْنِ عَبَّاسٍ، بِهَذَا الْحَدِيثِ قَالَ فِيهِ وَالاِبْتِهَالُ هَكَذَا وَرَفَعَ يَدَيْهِ وَجَعَلَ ظُهُورَهُمَا مِمَّا يَلِي وَجْهَهُ .
In another version Ibn 'Abbas said: Earnest supplication should be made like this: he raised his hand and made his palms in the direction of his face.
