“Abu Ja’far (a.s.), has said, ‘People would just drop dead. Ibrahim (Abraham), ‘Alayhi al Salam, pleaded before Allah, ‘Would that You had created a cause for death to be recognized thereby and for grieving people to receive condolence.’ Allah, the Majestic, the Glorious, then sent al-Mum, which is a kind of fever causing hallucination and thereafter He sent medicine.”
