Surah Al-Baqarah — Verse 76

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

Wa izaa laqul lazeena aamanoo qaalooo aamannaa wa izaakhalaa ba'duhum ilaa ba'din qaalooo atuhaddisoonahum bimaa fatahal laahu 'alaikum liyuhaajjookum bihee 'inda rabbikum; afalaa ta'qiloon

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 Allah has revealed to you so they can argue with you about it before your Lord?" Then will you not reason?
