Islam does not allow us to bully or oppress anyone. In a hadith we read that our beloved Prophet Muhammad (SAW) said:
“Beware of committing oppression, for oppression will be darkness on the Day of Resurrection. Beware of greed, for greed destroyed those before you. It caused them to shed blood and to make lawful what is unlawful.” (Hadith, Muslim)

It is important to understand that the effects of bullying are often more serious than we would imagine. Victims of bullying have experienced stress and trauma much later on in their lives even if they had been bullied at a young age. Adults experience bullying too, whether that is by people in the community, family and friends, or in the workplace. We must understand that this is not in line with the teachings of Islam. We read in the Holy Qur’an that Allah says:
“O you who have believed, let not a people ridicule [another] people; perhaps they may be better than them; nor let women ridicule [other] women; perhaps they may be better than them. And do not insult one another and do not call each other by [offensive] nicknames. Wretched is the name of disobedience after [one’s] faith. And whoever does not repent – then it is those who are the wrongdoers.” (Qur’an 49:11)
