Mocking someone's beard
Q:
1. I have one uncle whose beard has only few hairs. I had made fun of his beard saying that his beard has few strands of thread... I was actually making fun of his beard, not the sunnah... Also I did not know at that time that we should not make fun of beard... Did I do kufr? If yes, what should I do?
2. Some people call him chinese... did they also do kufr?
