[2:243] Have you not seen those thousands, who went forth from their habitations fearful of death? God said to them, 'Die!' Then He gave them life. Truly God is bounteous to people, but most people are not thankful.
When they viewed it farfetched that they would return by God's power, He showed them this directly in their own selves. The manifestation of that, however, did not benefit those who had not sharpened their insight regarding divine unity (tawḥīd). Anyone whose insight has been strengthened will not be harmed by a lack of these direct forms of evidence, for they have already confirmed what they have been told through their faith in the Unseen.
