Firstly, new discoveries have confirmed that some parts of ancient Greek sciences are not scientifically true while none of the scientific sayings of the Qur’an has been denied by significant and true scientific discoveries. (I mean that scientific sayings of the Qur’an do not contradict the true scientific findings)
Secondly, I want to ask a question that how could it be historically possible that an unlettered man was able to collect ancient Greek science. And how could it be possible for him to reorganize this science and use it in his book?
In actuality, from the beginning of the revelation of the Qur’an such allegations have risen from the people who have rejected the Qur’an. They do not want to affirm the Qur’an as a divine scripture, so they have been seeking human origin for its content. Indeed, what they have developed as arguments are not based on reality rather based on assumption. The history does not confirm any direct or indirect connections between the Prophet (S) and the scholars or scientists of his age.
The Qur’an clearly expresses its contemporary opponent’s statements in this regard. When we compare them with modern scholars’ justifications we see that how they are similar to each other:
وَقَالَ الَّذِينَ كَفَرُوا إِنْ هَذَا إِلَّا إِفْكٌ افْتَرَاهُ وَأَعَانَهُ عَلَيهِ قَوْمٌ آخَرُونَ فَقَدْ جَاءُوا ظُلْمًا وَزُورًا ـ وَقَالُوا أَسَاطِيرُ الْأَوَّلِينَ اكْتَتَبَهَا فَهِي تُمْلَى عَلَيهِ بُكْرَةً وَأَصِيلًا
And the disbelievers say, “This is naught but a lie that he has fabricated, and another people have helped him in it. They have indeed produced a wrongdoing and a calumny. And they say, “They are fables of those of old which he has had written down, and they are recited to him morning and evening.” (25:5-6)
وَلَقَدْ نَعْلَمُ أَنَّهُمْ يقُولُونَ إِنَّمَا يعَلِّمُهُ بَشَرٌ...
Indeed, We know that they say, “He has merely been taught by a human being.”… (16:103)
