God says in the Quran By the fig, and the olive, . By Mount Sinai, The Prophet Muhammad (PBUH) said: "Eat olive oil and use it as lubricant and lotion, for it comes from a blessed tree". . Medical researchers have listed the numerous benefits of olive oil; it is beneficial for the digestive system, the liver and is better than all other kinds of oils (of animal or plant origin) as it does not affect the circulatory system or capillaries as other oils do. It is also a good moisturizer that relieves the skin and increases its elasticity. It also has various uses in industry and is used in many chemical compounds for making cosmetics, food and medicine. Scientific implications in this ayah: Due to its unique character, the olive tree now has its own classification system for its genus within the order of flowering plants, order oleales. Prior to that, it was included in another order, known as contortae. This order includes one family known as the oleaceae family which is divided into two subfamilies, oleoideae and jasminoideae. The trees of the family oleaceae includes 28 genera and between 500 and 600 species of flowering plants which grow all over the world, except for cold areas and the Arctic. They grow mainly in temperate and equatorial regions, particularly the Mediterranean basin and southwest Asia. In spite of this broad range of habitats, the trees of this family are rarely dominant in a single area; some of the trees are evergreen, like the olive tree and others shed their leaves. The folded genera in order oleales have economic and aesthetic importance as shown in the olive trees, with its many types, fruits, oil and wood. There is also the ash tree which is well-known for its solidity. There are shrubs and creepers with fragrant scents such as lilacs and different types of jasmine. Olive trees are distinguished by their perennial nature whereby one tree can live for more than 2000 years. Two kinds of olive trees grow in Egypt; one is wrongly known as the European olive (olea europaea) and should be rightfully named as the Sinai olive (olea sinaensis). It was originally cultivated in the Sinai Peninsula and then in other parts of the Mediterranean basin. One of these types of olives is commonly known as "apple-like olives" (Zeitoun Toufahi), and bears relatively large fruits with little oil content which makes them suitable for pickling. They are widely cultivated in the western oases and in Al-Fayoum. The other kind of olive is known as "northern olives" (Zeitoun Shamaly); their fruits are relatively small and rich in oil content which makes them suitable for pressing. They are widely cultivated in the Sinai Peninsula and along the Mediterranean coast. The most important source of vegetable oil is the oily seeds that produce cottonseed oil, linseed oil, sesame oil, sunflower oil, castor oil, peanut oil and soybean oil. We can also obtain vegetable oils from some oily fruits like olives, coconuts and oil palms, or from the embryos of grains such as wheat, corn and rice. It has been medically proven that whenever bad cholesterol (LDL) levels drop and good cholesterol (HDL) increases, the chances of getting cardiac thrombosis are reduced and, in particular, getting cardiac muscle infarction. Consuming olive oil regularly protects the arteries from the possible clogging of blood vessels. This is very common at present, particularly in affluent countries where people usually eat until they are satiated. The lowest rate of coronary cardiac diseases was found in the Mediterranean region, particularly in countries where people consume olives and olive oil regularly. This is an indication to its active role in protecting the arteries, particularly as it has been proved that olives and olive oil contain chemical compounds that prevent blood coagulation. For this reason, doctors advise all patients who have had heart bypass operations to take 4 to 5 spoons of olive oil daily as part of their treatment. By mentioning olives and olive oil in several places in the Qur'an, as well as Allah taking an oath by it, confirms its nutritional value which has been proved by medical and scientific research in the twentieth century. These Qur'anic references prove the scientific miracle of the Holy Qur'an which was revealed 1400 years ago as well as the miracles of Prophet Muhammad (PBUH) to whom the Qur'an was revealed; he said, "Consume olive oil and use it as lubricant and lotion, for it comes from a blessed tree ". Many questions related to this issue come to mind, such as, why did Allah reveal this ayah in the Holy Qur'an? And why did He make the Prophet (PBUH) inform us about the olive tree, its fruit and oil? The answer to these questions is that Allah knows best in His all-encompassing knowledge; perhaps that one day, man will discover the benefits of olives and olive oil, making the Qur'anic ayah and the above Hadith witnesses to the fact that the Qur 'an is the Word of Allah. Praise be to Allah who blessed us with the Qur'an and Islam and revealed it to the best of mankind, the Seal of the Prophets and Messengers and the Imam of the honored. Praise be to Allah in this life and the afterlife, praise be to Allah in every time and epoch. May Allah's praise and peace be upon the loyal Prophet and his family, his companions and those who follow his true religion and invite to his message until the Day of Judgment.
