Whatever the mother eats, drinks or breathes during pregnancy, Allāh (SWT) also allots it to the child.”It is therefore very important that the mother takes care with the food that she eats.What appears to be the case that the view of those among the early generations who said that could only be based on experience and custom. For example, Medical research has determined that fresh dates contain a substance that contracts the uterus and strengthens uterine muscles, and helps with childbirth; it also reduces the amount of bleeding that occurs after childbirth.Similarly, they also contain a high amount of simple sugars that are easily digested, which is a basic source of energy and is important and beneficial for the muscles, especially the uterine muscles which play a big role during childbirth.

Cure of diseases through medicinal plant is always a salient feature of Islamic teaching and preaching. Islamic medicine started from Hazrat Adam (A.S.) and was completed at Hazrat Muhammad (SAW) but search and compiling of these medicines is still continued through out the world

They are rich in potassium and low in sodium, and thus help regulate the nervous system. Infact Dates contain thirteen elements of vital importance, and five types of vitamins, making it a rich food. The calcium in dates is essential for firming bones, the phosphorus for forming the brain and preventing weakness of the nerves and tiredness, and the potassium for preventing wounds/sores in the stomach.
