Miserliness and jealousy are sicknesses that lead to the soul hating that which would benefit it, and its loving that which would harm it. This is why jealousy was mentioned alongside hatred and resentment in the preceeding ahaadeeth. As for the sickness of desire and passionate love then this is the soul loving that which would harm it and coupled with this is its hatred of that which would benefit it.
Passionate love is a psychological sickness, and when its effects become noticeable on the body, it becomes a sickness that afflicts the mind also. Either by afflicting the mind by the likes of melancholy, or afflicting the body through weakness and emaciation. But the purpose here is to discuss its affect on the heart, for passionate love is the fundament that makes the soul covet that which would harm it, similar is the one weak of body who covets that which harms it, and if he is not satiated by that then he is grieved, and if he is satiated then his sickness increases. The same applies to the heart afflicted with this love, for it is harmed by its connection to the loved, either by seeing, touching, hearing, even think about it. And if he were to curb the love then the heart is hurt and grieved by this, and if he given is to the desire then the sickness becomes stronger and becomes a means through which the grievance is increased.
In the hadeeth there occurs, “Indeed Allaah shelters His believing servant from the world just as one of you shelter your sick ones from food and drink (that would harm them).”[1]
