Does death have a smell, and what do you say about someone who smells it?

What is happening to you is a type of psychological illness, and you should consult a doctor about it. Death is a truth, and for the believer, there is a great benefit in it because it brings tidings of meeting Allah and His pleasure, thus transitioning from constriction to spaciousness. Whoever fears death should prepare for it and make their fear healthy, not pathological. Disliking death is natural; even the Companions disliked it. As for cursing death, a Muslim should not curse anything and must be content with Allah's decree, for all His decrees are good and wise, and cursing death might be an objection to Allah's decree.
