Dates in general and dried dates in particular, especially from Medina, possess tremendous qualities and are especially effective in treating from heart ailments. Using seven dates is another quality that can only be known through the revelation.
In the sahihain it is narrated that Sa’d bin Abu Waqqas said, “ The Messenger of Allah (sallalaahu alaihi wasallam) , “ Whoever eats seven dates from the area of Al’ Aliab when he gets up in the morning then no poison or magic would harm him that day.”
Dates constitute a good type of nutrition, especially for those whose regular diet contains dates, such as people of Al-Medina. Dates are the best type of food for the residents of the hot and mildly warm countries, more so that for the residents of cold areas who have an elevated inner temperature, whereas those in warm areas have a colder inner temperature. This is why the people of Hijaz, Yemen and Ta’if and similar areas, eat hot foods such as dates and honey.
Dates are a type of fruit that is used for its nutritional and medicinal value, being favorable for most bodies and for their role in strengthening the natural heat. In addition, dates do not produce harmful wastes or excrements such as the other types of food and fruits. Rather, dates preserve the bodily wastes from being spoiled and from rotting, especially for those used to eating dried dates.
” It is a condition that the sick person should believe that the medicine will help him, so that his body accepts it and benefits from it . It is a fact that sometimes merely believing that the medicine will work helps cure some ailments, as many people have witnessed in this regard. When the heart accepts that a certain medicine carries the cure, the body will feel an elevation in its strength and in the instinctive heat that will help the body get rid of and extract harmful substances. On the other hand, sometimes an effective medicine fails to work because the patient does not believe that it will cure him, and consequently, his body neither accepts it, nor benefits from it.”
Even the Qur’an, which is the best, most beneficial remedy ever, both in this life and in the Hereafter, and which is a cure for every disease, will not benefit the heart and does not believe in its value as a cure and a remedy. Rather, the Qur’an only adds more disease to such evil hearts.
