Not Sent as a Sign
Those who do not expect to meet Us say, “If only angels were sent down to us, or we could see our Lord.” They have grown arrogant within themselves and have become excessively defiant.
25:21And those who look not for a meeting with Us say: Why are angels not sent down unto us and (Why) do we not see our Lord! Assuredly they think too highly of themselves and are scornful with great pride.
