Purity: Sufficiency of Wiping with Wet Hands in Washing Face and Arms During Wuḍūʾ

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 243

If a person wets his hand with water and wipes it on his face and arms, in the event that the wetness of his hand is to the extent that by wiping his face and arms the water covers them, it is sufficient, and it is not necessary for the water to flow over them.
