Question
If someone wipes over their khuffs and is able to see their heel from above, is it permissible for them to wipe over them?
Answer
I say, and with Allah is success: Seeing the heel of the foot from above does not harm; because the condition is to cover the heels from the sides, not from above. See: Al-Maraqi p.130, Radd al-Muhtar and Al-Durr al-Mukhtar 1: 174, and Allah knows best.
