Allahu Taala has related iman (which is the basis of Islam) to experimentation and the intellect. That is, the building of Islam has been erected upon these two principles. All other worships, blessings, and forms of obedience are the branches and twigs of this tree of iman. Allahu Taala, at many places of the Quran alKarim, scolds and disgraces disbelievers because they didn’t use their minds; they didn’t think by observing the earth, the skies and themselves, so that they could have attained iman. The book Marifatnama writes: “Sayyid Sherif Jurjani, a great Islamic scholar, says that the knowledge of astronomy helps a wise and reasonable person to realize the existence of Allahu Taala. Imam al-Ghazali says that he who does not know astronomy and anatomy cannot realize Allahu Taala’s existence and power.”
