Translation:

56. But those endued with knowledge and faith will say: "Indeed ye did tarry within Allah's Decree to the Day of Resurrection and this is the Day of Resurrection: but ye ye were not aware!"

Notes (Tafseer)

3574. The men of knowledge and faith knew all along of the true values-of the things of this ephemeral life and the things that will endure and face them at the End,-unlike the wrong-doers who were content with falsehoods and were taken by surprise, like ignorant men, when they faced the Realities.
