When reflecting on the verse it is understandable that the jealousy that was available in the brothers of Youssef drove them to throw him into a well, and even to think about killing Youssef, and they would have done it if the speaker among them had not turned off this fire.
Jealousy affects three groups of people negatively:
1- The jealous themselves, since jealousy is a door for mental illnesses that are highly irritating for the person who is jealous, in a way that Imam Ali (a.s) stated, “The ill-wisher’s soul is tormented”(2). Usually when children get jealous of someone, they spite them, which leads up to them tormenting their soul wanting to fulfil their wicked desire.
2- The family, as jealousy brings envy and envy brings hatred which is the cause of many problems. Imam Ali (a.s), stated “Envy brings disaster.”(3)
3- The society, since if this child does not fulfil their desire of envy on the person they envy, they will take it out on other kids which could harm them and cause hatred between parents.
