Hakeem al-Ummah Hadhrat Maulana Ashraf Ali Thanwi (ra) once said:

The sum total of good character is to avoid causing inconvenience to anyone. The Messenger of Allah sallahu ‘alayhi wasallam forbade anyone from lifting (hiding) the stick (such as a walking stick) of his Muslim brother even if it is out of jest, for this would cause him distress. Making people laugh at the expense of others is also prohibited due to the embaressment and inconvenience it causes.
