Hadith Narrated By Khalid bin Saad

"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 Aisha narrated to them that she heard the Messenger of Allah (saw) say: "This black seed is a healing for every disease, except the Sam." I said: "What is the Sam?" He said: "Death."
