1. My father said: it was narrated to me by Sa’d b. Abdillah from Ahmad b. Muhammad from al-Hussain b. Sa’eed from al-Hassan b. Ali b. bint Ilyas who said I heard al-Ridha saying that The Messenger of Allah (s.a.w.s.): “The Almighty Allah has cursed the one who causes something and one who hides him.” I asked: Who is that? He replied: One who kills.”
