Olive Oil.

Allah the Almighty speaks of the olive in the Holy Qur’an;

“...Lit from a blessed tree, an olive, neither of the East [so that it only gets the sun’s rays in the morning], nor of the West [so that it only gets the sun’s rays in the afternoon, instead it is exposed to the sun all day long], whose oil would almost glow forth (of itself), although no fire hath touched it.” 
[24:35]

And also;

"By the Fig and the Olive."
[95:1]

It was narrated by 'Umar (radhi Allahu anhu) that he heard the Messenger of Allah (sallallahu alayhi wasallam) say, "Season (your food) with olive oil and anoint yourselves with it, for it comes from a blessed tree."

Sunan Ibn Majah Book 29, Hadith 3444. Graded as Sahih by Darussalaam.

Since olives and their oil are mentioned in both the Qur'an and the Sunnah respectively, they are considered one of the primary healing foods and are therefore recommended to be consumed regularly.

The healing power of olive oil comes in part from its high levels of Mono-unsaturated fatty acids and antioxidants, and in part from the fact that it is well tolerated by the stomach, so it easily breaks down and is an excellent protective emollient for stomach ulcers and gastritis.

All kinds of olive oil are beneficial for softening the skin and slowing down both the skin aging and hair greying processes. It is also known as an anti-inflammatory and beneficial for all kinds of liver and gall bladder problems.

Studies have shown that people who consume around two tablespoons of extra virgin olive oil daily have a lower level of LDL cholesterol in the blood, leading to a lower overall risk of heart disease. Spanish researchers have also found links between olive oil and a reduction in the occurrence of both colon cancer and breast cancer.

The best possible type of olive oil to buy is cold-pressed extra virgin olive oil, which is greenish in colour and contains the highest possible levels of Vitamin E, antioxidants and phenols. This is because it is less processed than commercially refined olive oils. Olive oil is best kept tightly sealed in a cool dark place, as exposure to the air and a light, warm position promotes faster rancidity. Olive oil should be used in place of regular cooking oil in pasta dishes, sauces, stews and curries.

The brine in which olives are bottled is particularly beneficial for strengthening in the gums if used as a mouth rinse.

It is encouraged to use Olive Oil regularly as a moisturiser for the skin and hair.

The use of oil on the body can be traced directly to the Sunnah, where our Mother A'ishah (radhi Allahu anha) also narrated that "The Prophet (sallallahu alayhi wasallam) used to (put) bend his head (out) to me while he was in Itikaaf in the Mosque during my monthly periods and I would comb and oil his hair."

Sahih al Bukhari Volume 3, Book 33, Number 245

Olive oil is great for hair and over time, makes it shiny and silky and easy to manage. It's recommended to massage the scalp with your fingertips when applying olive oil so that its antioxidants are absorbed with greater ease. Olive oil is also used for hair loss, hair strengthening (prevention of split ends) and slowing down the rate of grey hair.

Olive oil is also used by Raqi's when they recite the Qur'an by Allah's Leave for people who are afflicted by sorcery. In sha Allah there is no harm in reciting the Qur'an on olive oil before using it.

Honey is from both the Qur'an and the Sunnah.

Honey is ma sha'Allah the most pleasing sweetener created and Allah the Most Exalted praises the Bee in the Qu'ran and mentions honey's healing quality;

"There emerges from their bellies a drink, varying in colours, in which is a healing for people. Indeed, in that is a sign for people who give thought."

[16:69]

Allah uncovers the hidden beauty of honey by mentioning that it varies in colours. The same bee can produce different colours of honey at different times of the year depending on which wild flowers it has visited.

Ibn al Qayyim (rahimullah) mentions that natural [organic] honey is the best of all nutritive sweeteners. Light-coloured honey which has had the minimum of processing and comes from mountainous or wooded areas is better than other types of honey. Honey contains detergent and tonic properties. Taking a spoonful of honey in the mornings helps dissolve phlegm, gently warms and strengthens the stomach and increases a person’s appetite. Drinks sweetened with sugar rather than with honey yield more harm than benefit. A cold drink of honey and water insha’Allah strengthens the body,preserves its youth, as well as refreshing the heart.

The Holy Prophet (sallallahu alayhi wasallam's) fondness for Honey;

It has been narrated by A'ishah (radhi Allahu anha) that "Allah's Apostle was fond of honey and sweet edible things and (it was his habit) that after finishing the 'Asr prayer he would visit his wives and stay with one of them at that time. Once he went to Hafsa, the daughter of 'Umar and stayed with her more than usual. I got jealous and asked the reason for that. I was told that a lady of her folk had given her a skin filled with honey as a present, and that she made a syrup from it and gave it to the Prophet to drink (and that was the reason for the delay). I said, "By Allah we will play a trick on him (to prevent him from doing so)." So I said to Sada bint Zam'a "The Prophet will approach you, and when he comes near you, say: 'Have you taken Maghafir (a bad-smelling gum)?' He will say, 'No.' Then say to him: 'Then what is this bad smell which i smell from you?' He will say to you, 'Hafsa made me drink honey syrup.' Then say: Perhaps the bees of that honey had sucked the juice of the tree of Al-'Urfut.' I shall also say the same. O you, Safiyya, say the same." Later Sada said, "By Allah, as soon as he (the Prophet) stood at the door, I was about to say to him what you had ordered me to say because I was afraid of you." So when the Prophet came near Sada, she said to him, "O Allah's Apostle! Have you taken Maghafir?" He said, "No." She said. "Then what is this bad smell which I detect on you?" He said, "Hafsa made me drink honey syrup." She said, "Perhaps its bees had sucked the juice of Al-'Urfut tree." When he came to me, I also said the same, and when he went to Safiyya, she also said the same. And when the Prophet again went to Hafsa, she said, 'O Allah's Apostle! Shall I give you more of that drink?" He said, "I am not in need of it." Sada said, "By Allah, we deprived him (of it)." I said to her, "Keep quiet." '

Honey as a medicine.

The use of honey as a medicine is directly traced to the Sahih Sunnah and therefore should be strongly promoted;

It was narrated by Ibn Abbas (radhi Allahu anhu) that the Prophet (sallallahu alayhi wasallam) said, "Healing is in three things: cupping, a gulp of honey or cauterization, (branding with fire) but I forbid my followers to use cauterization (branding with fire)."

Sahih al Bukhari Volume 7, Book 71, Number 585

And also;

It was narrated by Sa'id Al Khudri (radhi Allahu anhu) that a man came to the Prophet (sallallahu alayhi wasallam) and said, "My brother has some abdominal trouble." The Prophet said to him "Let him drink honey." The man came for the second time and the Prophet said to him, 'Let him drink honey." He came for the third time and the Prophet said, "Let him drink honey." He returned again and said, "I have done that ' The Prophet then said, "Allah has said the truth, but your brother's abdomen has told a lie. Let him drink honey." So he made him drink honey and he was cured.

Sahih al Bukhari Volume 7, Book 71, Number 588

The most anti-bacterial honey is ‘Manuka’, which is produced in New Zealand. It is renowned as the ultimate healing honey and comes in three main strengths, Active 5+, Active 10+ and Active 15+; the higher the numeric factor, the higher the anti-bacterial and antiseptic powers of the honey. Active 5+ or similar should be adequate to help treat digestive disorders, sore throats, acne, eczema and sunburn, and it can also help in the fight against gum disease.

I have personally found that the best honey for general consumption is that which is produced locally to where the patient lives and is unfiltered and organic. Local honey mixed with bee pollen is also an excellent treatment for the patient's summertime allergies like hayfever as it slowly build's up the patient's resistance to allergens.

Honey can also be used to treat wounds due to its anti-bacterial properties and it can also be used in skin treatments since it has the ability to soften, absorb and retain moisture. A very effective face pack can be made with one tablespoon each of besan (gram flour), honey, lemon juice and milk, mixed together and applied for 30 mins before washing off. This in sha’Allah helps soften skin and even out brown spots.

Honey should be excluded from the diets of infants under 12 months of age.
