“The cure for hatred is straightforward. One should pray for the person toward whom he feels hatred; make specific supplication mentioning this person by name, asking God to give this person good things in this life and the next. When one does this with sincerity, hearts mend. If one truly wants to purify his or her heart and root out disease, there must be total sincerity and conviction that these cures are effective.
Arguably, the disease of hatred is one of the most devastating forces in the world. But the force that is infinitely more powerful is love. Love is an attribute of God; hate is not. A name of God mentioned in the Quran is al-Wadud, the Loving one. Hate is the absence of love, and only through love can hatred be removed from the heart. In a profound and beautiful hadith, the Prophet said, "None of you has achieved faith until he loves for his brother what he loves for himself.”
