Question:
What is the ruling on a person that does not believe in wiping over the leather socks as a practice of the Prophet (s) and is it part of `Aqeedah – tenets of Faith?
Answer:
He is a person of innovation and one should not pray behind him due to his belief that wiping over the khuffs is not a Sunnah; however, there is no consensus that it is part of `aqidah to believe in its Sunnah character, hence Imam Abu Hanifa only said: “I FEAR disbelief (kufr) for one who denies it,” i.e. it may lead him to kufr without consisting in kufr by itself. And Allah knows best.
