The worst attribute for human beings is envy. The first one that had envy was shayṭān. He went from being the highest among the angels to the lowest because of his envy of Ādam (as). We must be happy and accept what Allāh ﷻ gives us. He ﷻ made us all different. We must follow the way of ṭarīqah to cure this illness of envy to slowly, slowly finish your ego.
