Allah's Messenger (ﷺ) said, "He who eats seven 'Ajwa dates every morning, will not be affected by poison or magic on the day he eats them."
Sahih al-Bukhari Book 70, Hadith 74
← Previous Hadith While we were sitting with the Prophet, fresh dates were brought to him. The Prophet (ﷺ) said, "There is a tree among the trees which is as blessed as a Muslim" I thought that it was the date palm tree and intended to say, "It is the date-palm tree, O Allah's Messenger (ﷺ)!" but I looked behind to see that I was the tenth and youngest of ten men present there, so I kept quiet' Then the Prophet (ﷺ) said, "It is the datepalm tree."

Sahih al-Bukhari Book 70, Hadith 73 Next Hadith → At the time of Ibn Az-Zubair, we were struck with famine, and he provided us with dates for our food. `Abdullah bin `Umar used to pass by us while we were eating, and say, "Do not eat two dates together at a time, for the Prophet (ﷺ) forbade the taking of two dates together at a time (in a gathering)." Ibn `Umar used to add, "Unless one takes the permission of one's companions."
