Is mocking people kufr?
Q: Suppose that I was explaining a question of maths to another person. He was weak in maths so he could not understand properly what I explained. Then I mocked at him that you couldn't understand this simple problem and others also laughed at him. Then, because I mocked at someone who was trying to learn something. Learning to score good marks and please his parents. Pleasing his parents to please Allah. So indirectly I mocked at him while he was trying to please Allah. Is this kufr indirectly? Mocking on a person who tried to please Allah.
