وَإِذَا لَقُوا۟ ٱلَّذِينَ ءَامَنُوا۟ قَالُوٓا۟ ءَامَنَّا وَإِذَا خَلَا بَعْضُهُمْ إِلَىٰ بَعْضٍ قَالُوٓا۟ أَتُحَدِّثُونَهُم بِمَا فَتَحَ ٱللَّهُ عَلَيْكُمْ لِيُحَآجُّوكُم بِهِۦ عِندَ رَبِّكُمْ ۚ أَفَلَا تَعْقِلُونَ

And when they meet those who believe, they say, "We have believed"; but when they are alone with one another, they say, "Do you talk to them about what Allāh has revealed to you so they can argue with you about it before your Lord?" Then will you not reason?

Al-Baqarah 76

وَإِذَا مَآ أُنزِلَتْ سُورَةٌ فَمِنْهُم مَّن يَقُولُ أَيُّكُمْ زَادَتْهُ هَـٰذِهِۦٓ إِيمَـٰنًا ۚ فَأَمَّا ٱلَّذِينَ ءَامَنُوا۟ فَزَادَتْهُمْ إِيمَـٰنًا وَهُمْ يَسْتَبْشِرُونَ

And whenever a sūrah is revealed, there are among them [i.e., the hypocrites] those who say, "Which of you has this increased in faith?" As for those who believed, it has increased them in faith, while they are rejoicing.

At-Tawbah 124

يَحْذَرُ ٱلْمُنَـٰفِقُونَ أَن تُنَزَّلَ عَلَيْهِمْ سُورَةٌ تُنَبِّئُهُم بِمَا فِى قُلُوبِهِمْ ۚ قُلِ ٱسْتَهْزِءُوٓا۟ إِنَّ ٱللَّهَ مُخْرِجٌ مَّا تَحْذَرُونَ

The hypocrites are apprehensive lest a sūrah be revealed about them, informing them of1 what is in their hearts. Say, "Mock [as you wish]; indeed, Allāh will expose that which you fear."

At-Tawbah 64

هُمُ ٱلَّذِينَ يَقُولُونَ لَا تُنفِقُوا۟ عَلَىٰ مَنْ عِندَ رَسُولِ ٱللَّهِ حَتَّىٰ يَنفَضُّوا۟ ۗ وَلِلَّهِ خَزَآئِنُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ وَلَـٰكِنَّ ٱلْمُنَـٰفِقِينَ لَا يَفْقَهُونَ

They are the ones who say, "Do not spend on those who are with the Messenger of Allāh until they disband." And to Allāh belong the depositories of the heavens and the earth, but the hypocrites do not understand.
