Curse is a Mercy

"The strong curses in Ziarat Ashura are all asking for goodness and mercy. With these material and sensual views of us, we think that goodness is always in health, strength, and life, regardless of the reality of life, from good or bad intentions, from good or bad will, and from good or bad beliefs. But this is not the case.

Life is good for man when he is a source of mercy for his own self and for others. But if he becomes the source of evil, and long life, and a lot of health and power causes a harm to one's self and the invasion of the privacy of humanity, then it is no longer good."

Sayyid Hashim Haddad (ra)
