al-Mughira ibn Shu‘ba, who mentioned the wudu’ of the Prophet (may Allah bless him and grant him peace), saying: Then he performed wudu’ and wiped over the two khuffs. He placed his right hand on his right khuff and his left hand on his left khuff, then he wiped their tops in a single wiping, until it is as if I am looking at the trace of his fingers on the two khuffs. Ibn ‘Aqil said: The Sunnah of wiping is like this, that one wipes his two khuffs with his two hands, the right for the right and the left for the left. Ahmad said: Whatever you do is permissible, whether with one hand or with both hands; and the statement of al-Hasan, along with what we have mentioned, are not contradictory.

Section: If one wipes with a rag or a piece of wood, it is potentially valid, because one has wiped over his khuffs, and it is potentially invalid, because the Prophet (may Allah bless him and grant him peace) wiped with his hand. If one wipes with one finger or two fingers, it suffices him if he repeats the wiping with them until it becomes like the wiping with his fingers. Ahmad was asked: Does one wipe with the palms or with the fingers? He said: With the fingers. It was said to him: Does it suffice to use two fingers? He said: I have not heard.

Section: If one washes the khuff, Ahmad was hesitant [to rule on its validity], but Ibn Hamid deemed it permissible, because it is more thorough than wiping. The Qadi said: It does not suffice him, because he was commanded to wipe and he did not do it, so it does not suffice him, just as if one were to throw dust on his face and hands in tayammum. However, if one passes his hands over the khuffs while washing or after it, it suffices him, because he has indeed wiped.

89 - Issue: He said: (And if he wipes its bottom to the exclusion of its top, it does not suffice him.)

We do not know anyone who said: It suffices him to wipe the bottom of the khuff, except Ashhab from the companions of Malik, and some of the companions of al-Shafi‘i, because he has wiped a portion of what is adjacent to the place of the obligation, so it suffices him, just as if he had wiped its top. The text narrated from al-Shafi‘i is that it does not suffice him, because it is not a place for the obligatory wipe, so wiping it does not suffice, just like the leg. We have already mentioned that the Prophet (may Allah bless him and grant him peace)...
