11. O believers, let not people mock other people [6], perhaps those (whom they mock) are better than them, neither women (mock) other women, perhaps those (whom they mock) are better than them. Neither should you defame one another, nor call one another by (offensive) nicknames. Wretched is the name (of) wickedness after (one has attained) the Faith. Whoever does not repent, then it is these that are the unjust.
[6]. There are seven things that Allāh hates: To look down on others, to tell lies, to shed innocent blood, to devise wicked plans, to walk to evil, to give false witness, and to sow discord among brothers.
