‘A’isha reported the Prophet as saying, “A family which has dates will not be hungry.” A version reports him as saying twice or three times, “A family which has no dates, ‘A’isha, will be hungry.”
Sa‘d told of hearing God’s messenger say, “He who has a morning meal of seven 'ajwa* dates will not suffer harm that day through poison or magic."
*The name of a good quality of Medina dates.
