Three Islamic inventions leading the global fight against COVID-19

With over 1.2 million cases recorded worldwide, the novel coronavirus pandemic has put the whole world on high alert. Fatalities have reached nearly 60,000 and if not for three inventions–soapalcohol, and quarantine–the number would be even higher.

The common trait between the inventions, aside from their efficiency in limiting the COVID-19 spread, is that Muslim scientists played a major role in their development.

Antibacterial soap

“Washing your hands with soap and water … kills viruses that may be on your hands,” reads the first recommendation on the World Health Organization’s (WHO) website.

Soap has been described as a savior since the start of the global COVID-19 outbreak, with health experts stressing the importance of regularly washing hands with water and antibacterial soap.

While there is evidence of soap-like materials dating back to around 2800 BCE in ancient Babylon, bathroom soap bars that we know today were first produced in the Middle East during the 10th century, the early days of what is commonly referred to as the Islamic Golden Age.

Persian physician, alchemist, and philosopher Abu Bakr Muhammad Ibn Zakariya Al Razi (854-925), known in the West as Rhazes or Rasis, described several recipes for soap-making.

The recipes first positioned Syria as a major exporter of soap to other parts of the Islamic world and to Europe. By the 13th century, soap production spread across the Middle East and North Africa region, with sources in Fez, Nablus, Damascus, and Aleppo.

Alcohol as a disinfectant

Alcohol has long been used by humans as an anaesthetic. Historians tracked the discovery of alcohol distillation, the production process of alcoholic drinks, to as early as 2000 BCE in the Indus Valley Civilization. However, the modern medical use of alcohol as a disinfectant dates back to the Islamic Golden Age.

In his medical encyclopedia “Al-Hawi,” translated to “The Comprehensive Book on Medicine,” Al Razi argues for the antiseptic use of alcohol on wounds before, during, and after surgeries.

The disinfection method was introduced in Baghdad’s first hospital, built in 805 by the Caliph Harun al-Rashid. The practice spread across the Islamic world thanks to its success in increasing the survival rate of patients who undergo surgery.

The discovery of alcohol’s disinfecting effect led European languages to adopt the substance’s original Arabic name (al-Kuhul), which means the “essence,” in reference to its distillation method.

Today, the global demand on medical alcohol has reached an unprecedented peak. Alcohol-based antiseptic gels have become an essential for keeping hands free from the coronavirus.

Quarantine to curb contagion

At the end of March, more than one third of the world’s population were under some type of quarantine. Many governments around the world enacted large-scale lockdowns to prevent the spread of the novel coronavirus.

There are a few historical records of isolations similar to today’s concept of quarantine. The first arguments for the use of quarantine to control the spread of diseases appeared in “The Canon of Medicine,” a five-volume medical encyclopedia compiled by Persian Muslim polymath Ibn Sina (980-1037), known as Avicenna.

Ibn Sina was the first to designate a method to avoid contagion through 40-day sanitary isolation. He called the method “al-Arba’iniya” (the fortieth), translated literally to “quarantena” in early Venetian language.

Quarantine was a mandatory practice in hospitals across the Islamic world to prevent the spread of leprosy, an infectious disease that causes disfiguring skin sores.

Quarantine became more common in Europe, especially in the meeting points of transcontinental merchants, such as Venice, during and after the Black Death plague in the 14th and 15th centuries. The term “quarantena” designated the forty-day period that all ships were required to be isolated before passengers and crew could go ashore.

The success of the method in controlling the spread of epidemics led to the survival of the term “quarantine” until today. Quarantine now designates all types of sanitary isolation, even when the duration is not forty days. Source:


  1. *Hadith of Prophet Muhammad ﷺ*

    1) *QUARANTINE* is a Prophetic ﷺ advice.*

    _”Do not enter a land where the plague (contagious ailment) has broken out ; don’t leave from where it has broken out”_
    Bukhaari (5739) and Muslim (2219)

    7) *THERE’S CURE*; patience is the virtue

    _The Prophet ﷺ said “There is no disease that Allah sent without sending for it a cure.“_
    Bukhari (Volume 7, Book 71, Number 582)


    _The Prophet ﷺ said: “Every disease has a cure. If a cure is applied to the disease, it is relieved by the permission of Allah.”_

    11) *HOME QUARANTINE* is a Prophetic advice

    _“The plague (contagion) patient who remains in his home with patience and expectation of reward, knowing that nothing will befall him other than Allah’s decree will attain the reward or a martyr“_
    Musnad Aḥmad, Sahih
    also Bukhaari (2829) and Muslim (1914)

  2. Ibn Sina’s Canon of Medicine contains no mention of a 40-day period of any sort in relation to spreading disease. I’ve personally done a thorough search of the entire Arabic text. Moreover, no Arabic nor English article claiming that Ibn Sina contributed to the idea of quarantine has any citation. It seems that people have tried to find something relevant to quarantine in Ibn Sina’s work and fallen victim to confirmation bias.

    Ibn Sina never mentions the number 40 in any such context, and the word quarantine is not translated from anything he wrote. The idea of distancing oneself from plague has been around forever, and of course is found within sahih ahadith. This does not detract from Ibn Sina’s enormous contribution to medicine. But people writing articles like this should be more responsible than to spread made-up information, especially without citation.

    Please do make a correction. I would recommend reading the original text, or at least reputable sources with proper cited research, before writing about these things.
