What is the criterion for a limb to dry during ablution, and is it sufficient for the previous limb to be wet when starting to wash the next limb? What is the ruling on a part of the arm drying after finishing wiping the head and ears due to obsessive doubts? How should a woman wipe her hair, and is it obligatory to wipe the entire ear?

The scholars differed on the criterion for muwalat (succession) in tahara (purification), holding two views: that it refers to custom, or that it is defined by the drying of the limb, which is the view of the majority of the companions. Muwalat is not interrupted by being occupied with removing dirt or repelling waswasa (obsessive whispers), as that is part of the purification. Consequently, the purification in the aforementioned scenario is valid. A woman's wiping of her head is like a man's wiping, and if she limits herself to wiping part of it, it is sufficient according to many scholars. Wiping the ears is a sunnah (definition) according to the majority of scholars. The questioner is advised to ignore waswasa and to take the easier opinions to avoid hardship.
