Mishkat al-Masabih 9 Supplications كتاب الدعوات 30

وَعَنِ السَّائِبِ بْنِ يَزِيدَ عَنْ أَبِيهِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا دَعَا فَرفع يَدَيْهِ مَسَحَ وَجْهَهُ بِيَدَيْهِ رَوَى الْبَيْهَقِيُّ الْأَحَادِيثَ الثَّلَاثَة فِي «الدَّعْوَات الْكَبِير»

As-Sa’ib b. Yazid, on his father’s authority, said that when the Prophet made supplication and raised his hands, he wiped his face with them. Baihaqi transmitted the three traditions in [Kitab] ad-Da’awat al-kabir .
