Why The Quran Does Not Mention The Vedas?
It is not correct to assume that people at that time were ignorant about such concepts. It is true that scientific discoveries in those fields were made much later, but people had such ideas for a very long time. For example, the ideas about evolution of species can be traced back to at least ca. 495-35 BCE. For details please see: Species Permanence and Change In Antiquity | Stanford Encyclopedia of Philosophy
Many Islamic scholars have affirmed the authenticity citing similar stories (the great flood at Noah a.s times, the first man – Adam which is a sanskrit word and Hawwa etc) and concepts (heaven and hell) which we read in Qur’an. Agreed, there might have been distortions like in Old and New Testaments, but it shouldn’t be discarded completely. It doesn’t seems a proper discourse. I’m just trying to understand honestly as to why just two scriptures are mentioned exclusively because behind each and every verse there’s absolutely a sound logic as to why its placed there and the choice of wordings. Jazak’Allah for your replies sir.
