Explanation & Benefits
Hafiz Abdush Shakoor Tirmidhi
Benefits: The aforementioned hadith establishes the benefits of black seed (kalonji), that it contains a cure for every disease except death, because the time of death is fixed. Even if a person uses thousands of medicines, the time of death is appointed; medicines cannot delay death. As Allah the Exalted says: ﴿وَلَنْیُّؤَخِّرَاللّٰهُنَفْسًااِِذَاجَاءَاَجَلُهَا﴾ (, al-Munafiqun: 11).... “And when the appointed time of someone comes, Allah does not grant them any respite.”
Hafiz Ibn Qayyim rahimahullah has mentioned many benefits of black seed in “Zad al-Ma‘ad.” Therefore, black seed should be used in one’s food and otherwise as well. The practitioners of medicine have written that black seed is very beneficial in the treatment of respiratory difficulties, cold, paralysis, facial palsy, migraine, and diabetes. If someone is bitten by a rabid dog, and black seed is continuously administered to them, the effect of the poison is eliminated.
