Know that its form in the timing of washing, in numbers, is the form of the head. We have mentioned that. The scholars agreed that the two men are among the parts of ablution, but they differed as to the form of its purity. Is that by washing, wiping, or by choosing between them? Whatever one of them does, the other is waived from it, and he has performed the duty if he does not. It is not necessary for them to be afraid, and our doctrine is that the choice and plural is better, and there is no saying except that there is one who says it, so wiping is according to the apparent meaning of the Book, and washing is according to the Sunnah, and the meaning of the verse is to refrain from the apparent part of it.
