Nor is there anything in Ahmad’s words to support this. It is difficult, if not impossible, and is an innovation with no basis in Islamic law. The inner surfaces of the fingers can scarcely cover the whole face. They only resorted to this in order to reserve some dust for the backs of the hands after wiping the face.
They may be answered as follows:
