All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Insulting and calling each other by offensive nicknames are reprehensible and dispraised morals which the Sharee’ah warned us against, so one should not play with those games that include these reprehensible morals, especially the young children. This is because they may learn these bad manners, and insulting and calling each other by offensive nicknames will be common in their tongue and this will become a firmly established conduct in them, whereas they must be nurtured on good morals and manners and not on bad ones.
Allah knows best.
