CHAPTER: Regarding ajwah dates.
Narrated Saad: I suffered from an illness. The Messenger of Allah صلی اللہ علیہ وسلم came to pay a visit to me. He put his hands between my nipples and I felt its coolness at my heart. He said: You are a man suffering from heart sickness. Go to al-Harith ibn Kaladah, brother of Thaqif. He is a man who gives medical treatment. He should take seven ajwah dates of Madina and grind them with their kernels, and then put them into your mouth.
Saad bin Abl Waqqas reported the prophet صلی اللہ علیہ وسلم as saying: He who has a morning meal of seven ‘Ajwah dates will not suffer from any harm that day through poison or magic.
