A Reminder for Those Who Miss the Scientific Impact of Islam

Assalamu alaikum, have you ever thought about how our faith directly sparked major scientific discoveries? Many don't realize that the drive for knowledge in Islamic civilization came straight from religious devotion. Dr. George Saliba, a professor at Columbia University, points out that Islamic society had a strong interest in astronomy because of religious needs like moon sighting, prayer times, and finding the qibla. These weren't concerns for the Greeks before us. He explains that astronomy and trigonometry show how religious practice and scientific thinking go hand in hand. New fields like ilm al-hay'a and advances in trigonometry were fueled by these religious motivations. Mosques used to fund and employ professional scientists, creating the role of the muwaqqit, or timekeeper. This person was a professional astronomer whose main job was to regulate prayer times and determine the qibla for the mosque. This unique office, with no parallel in other civilizations, is the best proof of the deep link between Islamic astronomy and religious needs. Dr. Seyyed Hossein Nasr, a historian at George Washington University, says that the Quran calls believers to study the cosmos as a form of worship. The Quran refers to natural phenomena as ayat, signs of God, and commands us to contemplate them. For a Muslim scientist, studying nature wasn't a secular thing; it was a religious duty, an extension of reflecting on the Divine Word. He adds that the goal of Islamic sciences was to discover the unity behind the diversity of the cosmos, reflecting Tawhid. By uncovering the mathematical laws of the universe, Muslim scholars believed they were revealing the Creator's wisdom, which strengthens faith through knowledge. Dr. David A. King, a historian of medieval science, notes that calculating the qibla from anywhere on Earth required solving complex spherical geometry problems, pushing the limits of mathematics and geography. The challenges of the sacred direction and prayer times motivated innovations that surpassed earlier achievements. Instruments like special astrolabes and sundials were made just for these religious tasks. Basically, Islamic astronomy was deeply responsive to community needs. Fixing the lunar calendar for Ramadan and festivals, along with daily prayer coordination, meant astronomical knowledge was woven into religious administration like nowhere else. In "Technology in the World of Islam," historian Ahmad Y. al-Hassan explains that Islamic jurisprudence (Fiqh) acted as a catalyst for engineering. The religious requirement for cleanliness, like doing wudu five times a day, drove advances in hydraulic engineering and water-raising machines. The hadith "Purity is half of faith" spurred the creation of aqueducts, public baths, and water networks to provide clean water for ablution. So, yes, faith was the engine. Let's see what the scientists themselves say. Al-Khwarizmi, the father of algebra, wrote in his book that he composed it to serve God and meet the practical legal needs of Islamic law. He was encouraged by the Caliph to make a useful work for things like inheritance, legacies, and trade, seeking God's favor and reward. Al-Biruni, a pioneer in many fields, said that seeking scientific truth is an act of worship commanded by the Quran. He cited the verse: "And they reflect upon the creation of the heavens and the earth..." (Quran 3:191). For him, astronomy and earth measurement were means to determine the qibla, prayer times, and witness God's perfection. Ibn al-Haytham, the father of optics and the scientific method, saw his empirical work as a spiritual journey to get close to God, the Truth. He directed his attention to light and vision, knowing God is the light of the heavens and the earth (Quran 24:35). He believed scientific truth brings us closer to divine reality. Al-Kindi said that pursuing truth is the same as the message of the Prophets. We shouldn't be ashamed to take truth from anywhere. Knowledge of things leads to understanding Divinity and Unity, which is what the true Prophets brought. Al-Ghazali stated that sciences like medicine, math, and astronomy are communal obligations (fard kifayah). Without them, society can't maintain justice and health. If no one masters them, the community sins; if someone does, the obligation is lifted. Studying these is an act of obedience to God. So, yes, scientific progress during Islam's golden age was precisely because of Islam. May this knowledge increase our love for our deen. Jazakallahu khairan.
