It is HE Who sends down rain from the skies; with it WE produce vegetation of all kinds: from some WE produce green (crops), out of which WE produce grain, heaped up (at harvest); out of the date palm and its sheaths (or spathes) (come) clusters of dates hanging low and near: and (then there are) gardens of grapes, and olives, and pomegranates, each similar (in kind) yet different (in variety): when they begin to bear fruit, feast your eyes with the fruit and the ripeness thereof. Behold! in these things there are Signs for people who believe. (Al-Aníaam - 99)
It is HE Who produceth gardens, with trellises and without, and dates, and tilth with produce of all kinds, and olives and pomegranates, similar (in kind) and different (in variety): eat of their fruit in their season, but render the dues that are proper on the day that the harvest is gathered. But waste not by excess: for ALLAH loveth not the wasters. (Al-Aníaam - 141)
In them will be Fruits, and dates, and pomegranates: Then which of the favors of your Lord will you deny? (Ar-Rahman - 68-69).
There are also hadith that mention the fruit:
Anas bin Malik (Radhiyallahu anhu) narrated that Rasulullah (sallallahu alaiyhi wassallam) said, "There is not a pomegranate which does not have a pip from one of the pomegranate of the Garden (of Jannah) in it." (Abu Nu'aim)
Rasulullah(sallallahu alaiyhi wassallam) said, "Pomegranate and its rind strengthen digestion(stomach)." (narrated Ali(radhiyallahu anhu), Abu Nuaim, Al-Jozi)
Some of the benefits of the fruit include that it has antioxidant, antibacterial and antimicrobial properties. In alternative medicine, it has been used to treat diabetes, heart disease, and cancer. Extract of pomegranate has been shown to fight against staph, salmonella and some kinds of strep bacteria. In the dental field, it has been found to inhibit the formation of the bacteria that causes plaque, aid in healing after periodontal procedures and reduce signs of chronic periodontitis. In a 2004 study by the Iran National Nutrition and Food Technology Research Institute, type II diabetes patients significantly reduced their cholesterol levels by consuming pomegranate juice concentrate daily.
The fruit is also used in many cures in traditional Islamic medicine.
