It is reported that if Hishām Al-Dustawā`ī – Allāh have mercy on him – didn’t have a torch on at home, he would toss and turn in bed until his wife would come with a torch. She asked him about this once, to which he replied, “If I don’t have a torch, I think about the darkness of the grave.”
Al-Dhahabī, Siyar A’lām Al-Nubalā`, in his biography of Hishām Al-Dustawā`ī.
