It was narrated that Khilid bin Sa'd said: "We went out and with us was Ghalib bin Abjar. He fell sick along the way, and when we came to Al-Madinah he was sick. Ibn Abu 'Atiq came to visit him said to us: ‘You should use this black seed. Take five or seven (seeds) and grind them to a powder, then drop them into his hose with drops of olive oil, on this side and on this side. For ‘Aishah narrated to them that she heard the Messenger of Allah say: “This black seed is a heaiing for every disease, except the sam.” I said: “What is the Sam?” He said: “Death.” (Sahih)
