وَلَوْ نَزَّلْنَا عَلَيْكَ كِتَٰبًا فِى قِرْطَاسٍ فَلَمَسُوهُ بِأَيْدِيهِمْ لَقَالَ ٱلَّذِينَ كَفَرُوٓا۟ إِنْ هَٰذَآ إِلَّا سِحْرٌ مُّبِينٌ
Important Words:

Commentary:
The words, and they had felt it with their hands, mean, "and they had made sure that it was a heavenly thing and not an earthly one". The words also embody a beautiful allusion to the spiritual blindness of the people. Being blind, they cannot see; so they have to feel with their hands.
The verse signifies that when a man gives himself up to doubting, nothing, however clear and manifest, can convince him.
They had made sure that it was a heavenly and not an earthly thing.
