Al-Hujurat · 49:11

11. O those who have faith in Allah and act upon what He has legislated! A group of you should not mock another; perhaps those that have been mocked are better according to Allah. True consideration is only for what Allah considers. And a group of women should not mock another group of women; perhaps the group mocked at is better according to Allah. Do not taunt the souls of your brothers, because they are like your own souls, and do not call others with names they do not like - as was the case of a few of the Anṣār before the arrival of the Messenger of Allah (peace be upon him). Whoever does that is a wrongdoer, and deviance is a very bad trait after having brought faith. Whoever does not repent from these sins are oppressing themselves by placing themselves in situations of destruction due to the sins they commit.
