Islam calls upon people to have good relations with one another and to avoid doing harm. We should avoid jealousy, which is a disease. The road is paved before everyone to excel in goodness as long as no harm is done to others. Dealing with jealousy starts by eliminating its causes, which are as follows: (1) Enmity (2) Ambition (it hurts a person to see someone else ahead or above him/her) (3) Pride and Arrogance. (4) Astonishment. (5) Fear (6) Desire for power and prestige. Etc. Normally jealousy occurs among people who know each other. It happens among siblings, among family members, people of the same profession and age. A Muslim must always keep in mind that jealousy is forbidden.
