Surah Hud (Hud) 11 : 110

Explanatory Note 

It is possible that they may not be destroyed, just as Moses’ people were not totally destroyed, despite the divisions and strife that arose between them over their faith and worship. God has decreed that they will be held answerable for all their deeds on the Day of Judgement.
 
There is a certain wisdom behind this decree. They were not totally destroyed because they had Scriptures. All those who received Scriptures, through any Prophet, will not be punished until the Day of Judgement. The Scriptures are clear pointers to the right path, and succeeding generations can study them and follow them, just as the generation which was first addressed by them. This cannot apply to physical miracles which are witnessed only by those who are present at the time they happen. Those who witness such miracles either believe as a result of what they see and thus save themselves, or continue to reject the faith and are punished in consequence. Both the Torah and the Gospel are full books, available to succeeding generations, until the final Scriptures are given, confirming both the Torah and the Gospel, and replacing them as guidance for all mankind. All people will be questioned on the basis of this final revelation, including the followers of the Torah and the Gospel. That is, concerning Moses’ Scriptures which were not written until much later, when its reports suffered much confusion. Hence, its followers are not fully certain of it.
