Is it permissible to wash the right heel with the right hand and the left heel with the left hand during Wudu? And is it permissible to convey water to the entire face over three times if it cannot be done in one go?

It is permissible to wash the limbs for ablution with the right hand, and there is no harm in washing the heel of the right foot with the right hand. Believing this to be forbidden is a blameworthy form of extremism. As for the claim of not being able to wash the entire face in one go, it is refuted; whoever takes water with both hands and pours it on their face can easily reach the entire face. What is required is to wash the entire face by any means, and washing means the flow of water over the limb, and a small amount of water is sufficient for that. If the washing of the face is not comprehensive in the first attempt, it is obligatory to wash whatever parts were not reached by the water. One must be wary of extremism and excessive scrupulosity.
