It mentioned that the Prophet indicated to Suhaib that he should abstain from eating dates when he was suffering from conjunctivitis, and did the same with ' Ali (Radiyallahu Anhu) when he was suffering from the same condition. Furthermore, Abu Na'im narrated in his book, Whenever any of the Prophet's wives would come down with conjunctivitis , he would not touch her until her eyes were cured.
"Conjunctivitis is an infection that attacks the conjunctiva, that is, the white part of the eye. The disease is caused by one of the four conditions [hotness , coldness, dryness and wetness], or by the accumulation of hot flatulence in the head and body, that later reaches the eye and cause conjunctivitis. When the eye is injured, the blood and the soul will rush to the aid of the affected eye, which then becomes swollen.
We should know that there are two types of moistures that ascend to the air. One is hot and dry and the other hot and wet. These moistures form the clouds that shade the sky from our eyes. Likewise, gaseous substances and moistures ascend from the stomach to the upper parts of the body and cause many ailments, such as conjunctivitis.
When the body's resistance is strong, it will push these gaseous substances to the nose and cause a congestion that usually accompanies colds. When these substances are pushed up through the uvula and the nostrils, they cause angina. When these moistures are pushed towards the side, they cause causes pleurisy, and when they reach the chest they causes pneumonia. When the moistures reach the heart they cause rapid pulse, and when they reach the eyes they cause conjunctivitis. When they reach the intestinal cavity, they cause diarrhea and when they reach the brain they cause forgetfulness. If the brain receives excessive amounts of these gaseous moistures, they might cause heavy sleeping. This is why sleep is wet while being awake is dry.
When the septic gases unsuccessfully seek to depart from the body through the head, they will cause headaches and less sleep. When these gases attack one side of the brain, they cause migraines. If these gases reach the cerebral barrier and cause its coldness, hotness or wetness, it will cause sneezing. If the gases cause the accumulation of phlegm in the cerebral barrier, so that its hot nature becomes weak, they may cause unconsciousness and a stroke.
If the gases excite the black bile, they will cause obsession, and if they reach the nerves, they will cause true epilepsy. When the cerebral nerves receive these gases they will suffer from facial paralysis. If these gases are caused by inflamed yellow bile that heats the brain, they will cause cerebral tumors, and when the chest receives a part of these gases, they will cause pleurisy.
In short, the condition of the head and body will be irritated because of conjunctivitis, and having sexual intercourse in this state will only aggravate the condition even more. Intercourse entails a movement that is shared by the entire body, the heart and the soul. As for the body, heats up due to the intense movements during sexual intercourse, while the heart will seek to obtain the object of its lust and pleasures. The soul will follow the lead of the body and the heart, as the first part that is connected to the soul is the heart, which in turn affects the rest of the body. As for the body, it sends the semen that is needed to bring the sexual intercourse to conclusion. Thus, sexual activity involves a movement by the entire body, the heart and the soul, and every move excites the various conditions and causes them to move to the weaker parts of the body, such as the eye when suffering from conjunctivitis.
We should state that the body benefits from conjunctivitis in that it helps the body extract harmful substances and cleanses the body and the head from septic elements. Conjunctivitis also compels the affected person to observe abstinence and avoid sadness, grief, strong movements and hard work. Further, one of our righteous predecessors said, " Do not hate conjunctivitis, because it prevents blindness.
"In addition, conjunctivitis requires rest and avoiding touching the eye to prevent more harmful substances from accumulating in it. Some of the Salaf once said, "The example of the Companions of Muhammad is like the example of the eye : its cure is in avoiding touching it.
A Hadith (the authenticity of which we are sure about) states that sprinkling cold water on the eye helps coreenjunctivitis. The remedy mentioned in the Hadith is beneficial for hot conjunctivitis, since water is cold and thus cools down the heat that accompanies conjunctivitis. This is why when the wife of ' Abdullah bin Mas'ud (Radiyallahu Anhu) complained about her eyes, he said to her, If you had done what the Prophet (PBUH) used to do, it would have been better for you and would have brought fast healing to your eyes. Splash water on your eyes and then say: Cure the ailment, O Lord of the people! Bring about the cure, for You Alone bring the cure and there is no cure except that which you bring about. Bring a type of healing that eradicates every ailment.
"We mentioned before that these types of remedies are suitable for certain areas and for some ailments that attack the eye. Do not understand the Prophet's statements that are specific to be general or vice versa. Otherwise, mistakes will certainly occur.
