Attitude of believers and hypocrites towards the revelation of Quranic verses

When a Surah is revealed some of them remark: "Whose faith among you has it increased?" It does increase the faith of those who believe, and they rejoice.

But it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving.

Do they not know that they are tried every year once or twice? Even then they do not repent and take heed.

Whenever a Surah is revealed they look at each other (so as to ask): "Is anyone looking at Us?" and then turn away. Indeed God has turned their hearts away (from the truth), for they cannot discern the law of heaven.
