Multiple Meanings In The Quran
Please read the article shared by Umer Qureshi sahab above and then listen to the old Meezan lectures where Ghamidi sahab discussed this topic at length. After you understand Quran’s verdict on this topic, if you find any questions regarding what’s already explained we can definitely present those to Ghamidi sahab or Hassan Ilyas sahab for further elaboration. Simply stating benefit to the humanity when the idea stands in stark contrast to God’s word is not an evidence. Besides I am not even sure what benefits for the humanity you’re citing.
If you think that we can put multiple meanings to that very word of God and still benefit in this world and the hereafter then I rest my case! The problem with the Quresh and the ahl-e-kitab that prophet Muhammad SAW addressed was not that they didn’t know about God or the hereafter. In fact to the contrary, not only that they were well aware of these concepts but were in fact quite religious from today’s standards. However, they had understood religion incorrectly and had innovated a lot of religious beliefs. Quran addresses this very topic and rejects the baseless claims that they were making. I think if you read a plain translation of the Quran yourself, you will get a better understanding of the matter and will change your mind.
