Question:
His Eminence, our revered father, Shaykh ʿAbdul-ʿAzeez ibn ʿAbdullāh ibn Baaz, Grand Mufti of the Kingdom—may Allah protect him from all harm.
Peace, mercy, and blessings of Allah be upon you. To proceed:
I have a question for which I kindly request Your Eminence’s answer. The question is:
What is the ruling on wiping the face with the hands after supplication, especially after the supplication of qunūt and after supererogatory prayers? May Allah preserve and reward you. Peace, mercy, and blessings of Allah be upon you.
Answer:
And upon you be peace, mercy, and blessings of Allah. To proceed:
Its ruling is that it is recommended (mustaḥabb), based on what al-Ḥāfiẓ (Ibn Hajr Al-Asqalani) mentioned in Bulūgh al-Marām in the chapter on remembrance and supplication—the final chapter of the work—that several hadiths have been narrated concerning it, the aggregate of which indicate that it is a ḥasan hadith. May Allah grant success to all. Peace be upon you.
A personal question answered by His Eminence on 12/9/1419 AH. (Majmūʿ Fatāwā wa-Maqālāt ash-Shaykh Ibn Baaz, 26/148).
(12/9/1419 AH corresponds to Wednesday, 30 December 1998 CE. This was around 5 months before his death in 13 May 1999. We must note that he had previous Fatwas where he said that wiping the face after Dua isn’t a prescribed Sunnah.)
