Are the misfortunes that have befallen my relative in her marriage, such as the loss of her pregnancy and the continuous problems with her husband, due to my supplication against her out of envy and wishing for the blessings to be removed from her? And is there a way to rectify her situation with her husband without her knowing about my envy of her?

Envy is a harmful disease with serious consequences for the one who harbors it, and Islam has prohibited it, as the Prophet Muhammad (peace be upon him) said: "Do not envy one another." Envy is wishing for the removal of blessings from someone who rightfully possesses them. Scholars have classified its degrees and rulings, and they have pointed out that three things are difficult to avoid: superstition, suspicion, and envy. The way to overcome them is by not acting upon them.

Envy exists in everyone, but it only becomes harmful when it turns into words or actions. It is forbidden to let envy lead to injustice and oppression, and if it does not go beyond mere feelings, it does not result in harm. If your envy did not extend beyond fleeting emotions or a passing supplication, it cannot be definitively said that you were responsible for what happened to your relative. However, it is always advisable to pray for her well-being, keeping your heart free from any negative impact.
