Surah 23. Al-Muminun, Ayah 63

This passage obviously connects with the last sentence of verse {56} - "Nay, but they do not perceive [their error!''-and. hence, refers to the people spoken of in verse {54} as being "lost in their ignorance" (fi ghamratihim ).

Namely, actions and dogmatic assertions which utterly contradict the teachings of the very apostles whom they claim to follow, like ascribing divine qualities to beings other than God, worshipping saints, or rejecting divine revelations which do not accord with their own likes and dislikes or with their customary mode of thinking.

 This refers to the believers’ good deeds mentioned in 23:57-62.

This is said of the Unbelievers who rejected Faith and rejoiced in the vanities of this world. In spite of the proclamation of Truth, they are doubtful of the future Life and Judgment.

In addition to their rejection of Faith, they have against them positive deeds of wrong-doing, from which, on account of their contempt of the Light from Allah, they will not desist until they are sharply pulled up for punishment: and then repentance will be too late!
