It was narrated that Khalid 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 and 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 nose with drops of olive oil, on this side and on this side. For ‘Aishah narrated to them that she heard the Messenger of Allah ﷺ say: “This black seed is a healing for every disease, except the Sam.” I said: “What is the Sam?” He said: “Death.”
