As it can be understood, the irreligious from among scientists have either rightfully attacked the things which the priests and the ignorant populace have misunderstood, or they have denied their imaginary beliefs that were understood with their minds, as a result of being convinced about the scientific information of their time. If they had read and understood the scientific information which Islamic savants had derived from the Qur'an with its subtlety and correctness, they all would have seen the fact and become Muslims willingly. While explaining the eighth ayat of Naml Sura, "You see the mountains stand motionless, but in fact they are moving like clouds," Qadi Baidawi states, "The mountains which, as you see, seem to stay in their places, are traveling fast through space. When big objects move speedily in a direction, those who are on it do not feel its motion." In the interpretation of the thirty-third ayat of Anbiya Sura, Fakhraddin-i Radi writes that Dahhak and Kalbi said that the moon, the sun and the stars rotated about their axes and revolved in their orbits. While explaining the twenty-ninth ayat of Baqara Sura, Fakhraddin-i Radi says, "Asiruddin-i Abhari, the author of the physics book Hidaya and of the logic book Isaguji, used to teach with the astronomy book entitled Majasti by Ptolemy. Somebody who considered the use of such a book as intolerable asked him with a harsh voice why he was teaching it to Muslim children. He answered that he was interpreting the sixth ayat in Sura Kaf which purports, "Don't they see how beautifully I have created the earth, the skies, the stars, and the planets?' thus giving him a beautiful reply." Imam-i Radi writes in his interpretation that this reply of Abhari's was correct and stated that those scientists who observe Allah's creatures understand the infinitude of His power very well.
The most important reason why prophets and holy books were sent and the first command that is absolutely necessary to be communicated is to declare that the Creator of the heavens and earth exists, that He is one, that He has superior attributes such as knowledge and others, and that His power and greatness are infinite. Because most people believe the things which they see and hear as they see and hear them and cannot understand their inner natures and delicate particulars, Allahu ta'ala, in His books, described the moon, the sun and the stars, which are the symptoms of His existence and greatness, the biggest and the most obvious creatures, which amaze people very much and which seem precise in every respect, so that every sort of people could understand them. By not explaining their calculations, laws and inner natures, He did not force the ignorant majority to busy themselves with the things which they could not understand, and He encouraged the intelligent, wise and distinguished among mankind in every century to understand them by studying them. Man's discoveries have been changing in process of time; those discoveries that were thought of as correct and dependable at one time have been understood to be wrong afterwards. Because the people of each century have believed in the correctness of the latest discoveries of their time, the beliefs of each century has been different from those of the others; these beliefs did not become sins or a matter of disbelief, for the beliefs that are sinful are those which disagree with the prophets' books and which deny what is stated in them. To protect His slaves against disbelief and sins, Allahu ta'ala did not explain scientific knowledge, which not everybody could understand, in His books, but He only pointed it out, and by describing the earth, the sun and the skies as they appear, He commanded us to take a warning from them and to understand His existence and His greatness. While explaining the command, "Introduce Me to My slaves through hikmat and through beautiful preaching!" which is in the hundred and twenty-fifth ayat of Nahl Sura, Qadi Baidawi says, "It means, "Communicate to the intelligent and to the educated through scientific knowledge and to the ignorant populace, who follow their emotions, by describing what is seen.' " At one time, upon reading about the things that were declared as they appeared in their books, Jews and Christians thought that the facts were so that the earth was smooth and motionless and that the sun was turning around it, that the sky was put over the earth like a tent, that Allahu ta'ala sat on a throne, like a man, and managed all affairs. Because scientific knowledge, which is discovered through experiments, disagreed with these beliefs of theirs, they said that scientists were irreligious. Upon this unjust Judgement, scientists attacked Judaism and Christianity. For example, William Draper, who is famous for his enmity against religions, says in his book Conflict Between Knowledge and Religion, "There is no human being who is apart from the universe, dominating the universe, and can do what he wishes." This word of his shows that he thinks of Allahu ta'ala as a human being and therefore denies Him. At another place, by stating, "There is a power in the universe which dominates everything, yet this is not the god whom the priests believe," he indicates that he thinks that Allahu ta'ala should be the greatest of the powers of physics and chemistry.
