Was the flood at the time of Prophet Nuh A.s Global or local?

“You know what is very interesting about the Qur’ān? Well, the Qur’ān seems to address various levels of intellect and addresses different levels of understanding at different periods in human history. For example, in chapter 23 verse 14 of the Qur’ān, it mentions the word ᶜalaqah to described a stage of the development of the human embryo. This word can mean a blood-clot, something that clings and a leech or a worm. The knowledge that was available during the 7th century maintained that the embryo was like a blood-clot and that it is something that clings. Interestingly in the 21st century the embryo on a microscopic level looks like a leech, even the internal structure of the leech looks like the embryo at around 4 weeks in its development. The word leech can also imply that when we were embryos we drained our mothers resources, just like a leech does, so we should love our mothers more and lower the wing of mercy and humility because they willingly sacrificed for us. This is an interesting aspect of the Qur’ān, it seems to be able to address various times and different levels of understanding. If some statements do not seem to be in line with modern science, then science will catch up. I have already shown how the Qur’ān can be from God without using science, and therefore we can conclude that what God says is true. Also, and as you know, science is not absolute, it changes with time and that there is always the possibility of new observations and new findings.”

It is my firm belief that any logical argument can be defeated by a more experienced and cunning debater.

Deen is ishq. It is not daleel. Daleel only leads to some understanding but it is ishq which brings a person deeper in it's ocean.
