Black seed is a cure.
Aisha (may Allah be pleased with her) said that she heard the Messenger salallahu alayhi wa sallam say, “This black seed is a cure for every disease except death.” [Saheeh al-Bukhaari (5687)].
Khalid bin Sa’d y 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 then apply them to his nostrils with drops of olive oil on this side and on this side for Aisha (may Allah be pleased with her) narrated to them that she heard the Messenger salallahu alayhi wa sallam say, “This black seed is a cure for every disease except death.” [Saheeh Sunan ibn Majah (3449)].
Ibnul Qaiyum (may Allah have mercy upon him) said, “It has immense benefits and his statement that it is a cure for every disease except death is like the statement of Allah,
{تدمر كل شيء بأمر ربها}
It destroys everything by the will of its Lord.
[Soorah al-Ahqaaf :125]
[Zaad al-Ma’aad 4/297].
Ibnul Qaiyum (may Allah have mercy upon him) said, “The black seed helps against all types of cold ailments… when ground, blended with honey and drunk with some water, it will dissolve the stones that appear in the kidney and the prostate…it increases the flow during menstruation and the production of milk if it is drunk for several days… When it is heated with vinegar and placed on the stomach it will eliminate worms. It also clears up, decomposes and relieves cold symptoms when it is ground, placed in a rag and inhaled through the nose on a regular basis until the ailment is cured. Black seed oil… when twenty-five grams of it is drunk with water, it will help against gasping and hard breathing…”. [Translated ‘Medicine of the Prophet’ by Ibnul Qaiyum (may Allah have mercy upon him) with slight modifications].
