God says, “Then perform tayammum on clean earth and wipe your faces and your hands from it.” The scholars, may God be pleased with them, differed regarding the limit for the hands in this purification. Some say that its limit is the same as its limit in ablution, and some say it is wiping the palm only, and some say that it is recommended to cover the elbows and the palms are obligatory. And who says that the obligation is up to the limits, which I say is that the minimum of what is called a hand in the Arabic language is obligatory, so whatever exceeds the minimum called the hand to its purpose, that is for him, and it is desirable in my view.
