Laughing at someone who does not handle a deeni book with respect
Q: Once, a hadeeth kitaab was sent to the copy shop. The workers there were not handling the kitaab with care for which some students teased the one who owned the kitaab. Is this tantamount to kufr? I believe that they were laughing at the way the workers were handling the kitaab and not looking down on the kitaab itself.
