The ruling on raising the hands for supplication and wiping the face with them

Question:
When are the hands raised during supplication?

Answer:
The hands are raised in every supplication, in all supplications, except for the supplications in which the Prophet (peace and blessings be upon him) did not raise his hands. For example, the supplication in the Friday sermon; the hands are not raised because the Prophet (peace and blessings be upon him) did not raise his hands. Likewise, in the Eid prayer, the hands are not raised in its sermon. Likewise, between the two prostrations, the hands are not raised. Likewise, at the end of the tashahhud and supplication, the hands are not raised because the Prophet (peace and blessings be upon him) did not raise them. Likewise, when one says the taslim to end the prayer, the hands are not raised because the Prophet (peace and blessings be upon him) did not raise them.
As for supplications that did not exist in his time (peace and blessings be upon him) in the sense that he did not raise his hands in them, then the hands are raised. For example, in the prayer for rain, the Prophet (peace and blessings be upon him) raised his hands. And so it is with the rest of the supplications.
Raising the hands in supplication is among the causes of the supplication being answered. However, in the supplications that the Prophet (peace and blessings be upon him) performed without raising his hands, it is not prescribed for us to raise our hands, because if it had been good, he (peace and blessings be upon him) would have preceded us in doing it. He supplicated between the two prostrations and did not raise his hands. He supplicated at the end of the prayer and did not raise his hands. He supplicated in the Friday sermon and did not raise his hands.
When some of the Companions saw Bishr ibn Marwan raising his hands in the Friday sermon, they disapproved of that, and the Prophet (peace and blessings be upon him) did not raise his hands in the Friday sermon.
Q: In qunut, the hands are raised, may Allah reward you?
The Shaykh: As for qunut, yes. It is established that he (peace and blessings be upon him) raised his hands in qunut in times of calamity.
Q: Does one wipe the face with them?
The Shaykh: Regarding the face, there are weak hadiths about it. So whoever leaves it, it is perhaps more appropriate, because the authentic hadiths do not include wiping. And whoever does it, some scholars have said it is permissible. Some scholars said that although the hadiths are weak, they strengthen one another and become hasan li-ghayrihi (good due to external support). This is what al-Hafiz Ibn Hajar said in "al-Bulugh" — at the end of "al-Bulugh" — he said: This is of the category of hasan (good).
For this reason, some scholars held the view that one wipes one's face with the hands after supplication. However, the authentic hadiths do not include wiping. So it is better to leave that, in accordance with the authentic, established hadiths. He (peace and blessings be upon him) supplicated in the prayer for rain and did not wipe his face. And he supplicated in many places, as established by authentic hadiths, and did not wipe his face.
