Can you mention a hadith where it says that we should wipe our face with hands after the dua?

In the name of Allah, the most Beneficent, the most Merciful.

Answer

Saaiduna Umar bin Khattab Radiallahu Anhu narrates that the Prophet of Allah Sallallahu Alahi Wasalam when he used to raise his hands in supplication he did not place them down until he wiped his face with them (Sunan Tirimizi)

From the aforementioned hadith we can deduce it is established through hadith to wipe your face with the hands after supplication.

Only Allah Knows Best
