1. Is it valid to rub the organs of tayammum while wiping with dust, as is valid in wudu’ with water, or does tayammum become invalid if dust passes over the limb more than once? 2. Is rubbing the hands together and interlacing the fingers in tayammum considered a mistake, and why are the sides of the fingers wiped by rolling? 3. Is the limit of the face in tayammum for women and those who shave their beards up to the jawline, as it is in wudu’?

The jurists have multiple opinions regarding rubbing (dalk) in tayammum, the extent of the face in it, and repeating the wipe. Rubbing refers to applying pressure to something when wiping or washing it, and the jurists have differed on its desirability. As for repeating the wipe, meaning passing the hand more than once with new dust, they have unanimously stipulated its detestability. However, none of them have said that tayammum is invalidated by rubbing or repeating the wipe. As for interspersing the fingers, it is desirable and involves interlocking the fingers and inserting the fingers of one hand between the fingers of the other. The limit of the face in tayammum is like its limit in ablution, and the majority have stated the obligation of wiping its entirety.
