Ishaq ibn Abi Isra'il narrated to us, Hammad narrated to us, Hanzalah narrated to us, from Anas: A woman came to the Prophet, may Allah bless him and grant him peace, and he wiped her face. They used to come to him, and he would wipe their faces and pray for them. She said, "O Messenger of Allah, lower your hand." He said, "Get away from me."
