عَنِ السَّائِبِ بْنِ يَزِيدَ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ إِذَا دَعَا فَرَفَعَ يَدَيْهِ مَسَحَ وَجْهَهُ
It is narrated from Sayyiduna Yazid (may Allah be pleased with him) that when the Noble Prophet (peace and blessings be upon him and his family) would supplicate, he would raise his hands and then (at the end) wipe them over his face.
