How to Do Khilal of the Toes
Question
What is the method of khilal (passing the finger between) the toes?
Answer
The little finger of the left hand is inserted between the little toe of the right foot and the toe next to it in such a way that it reaches not only the space between the two toes but also the underside of the toes; then khilal is done between the next two toes, and in this way khilal is done of all the toes.
