"Do they not consider the Qur'an? Had it been from any other than God, they would surely have found therein much discrepancy. [Qur’an 4:82]"
Do they not carefully consider (investigate) the Qur’an or are there locks upon their hearts. [Qur’an 47:24]
A scientific approach has been encouraged in the Qur’an with the objective of ascertaining its truthfulness. It provides man with a chance to verify it authenticity.
