8- Eye drops:
It is medically known that eyes have channels connected to the nose and throat, so it is an access to the throat. Contemporary scholars have differed regarding whether they invalidate the fast or not. A group of them holds the view that they do not affect the fast because fasting is proven by certainty and certainty cannot be removed by doubt. In addition, the amount of eardrops which reach the throat is little. So, they are few drops that are absorbed by the lacrimal canal before reaching the throat. However, if any drops reach the throat, they will be few and do not affect the fast; this is the view of Shaykh Ibn Baz and Shaykh Al `Uthaymeen (may Allah bestow mercy on their souls).
9- Therapeutic injections, whether they are sub-cutaneous, intramuscular, or intravenous:
The most correct view is: they do not take the same ruling of food and drink, and they do not have the same meaning, therefore they do not affect the fast. The international Islamic Fiqh Academy as well as multiple accredited bodies reached a decision in this concern to the extent that some people considered it a unanimous opinion.
10- Nutritious injections:
They are given to some patients and they are consisted of aqueous solution containing sugar, salts, and water, and possibly some medications were added to it. These injections are taken through veins; although these injections do not enter the body from the usual access for food and drink, they benefit the body as food and drink do. Hence, they invalidate the fast according to the correct view of contemporary scholars because it takes the same ruling of things that invalidate the fast which were mentioned in the Qur’an and the Sunnah.
11- Creams, ointments, and plasters:
It is known that skin has pores through which it absorbs anything is placed on it. So, when a person places fatty substance on his skin, the skin absorbs this substance immediately. Sometimes, treatments are placed in the form of plasters which contain a jet substance or pain killers. In some cases, it produces substances that help prevent pregnancy, or to stop smoking. The International Islamic Fiqh Academy unanimously adopted the view that these things do not affect the fast because they are not food, drink, or even nutrition; moreover, they do not enter the body from the usual access. In addition, at the time of the Prophet (peace be upon him) people were in need to use creams on their skins and their hairs, however, if they invalidate the fast, the Prophet (peace be upon him) would warn the people against using them.
