“One group of people should not make fun of another group of people. May be they (the latter) are better than they (the former)”.
(Surah al-Hujurat, 49:11.)
Some people make fun of others, and humiliate them in the eyes of their fellow-beings. People who speak ill of others, are usually those whose education and upbringing have not been up to the mark, and who have not learnt proper social manners. They are not perhaps, aware that all human beings are equal, and no one has the right to humiliate or hurt another. They also forget that it is quite possible, that those whom they ridicule may in fact be better people than themselves, because of their good qualities.
It is the duty of every Muslim to respect others. If he observes any defect in the body, dress or house of another, he should not laugh at him or ridicule him.
