2:76
وَإِذَا لَقُوا۟ ٱلَّذِینَ ءَامَنُوا۟ قَالُوۤا۟ ءَامَنَّا وَإِذَا خَلَا بَعۡضُهُمۡ إِلَىٰ بَعۡضࣲ قَالُوۤا۟ أَتُحَدِّثُونَهُم بِمَا فَتَحَ ٱللَّهُ عَلَیۡكُمۡ لِیُحَاۤجُّوكُم بِهِۦ عِندَ رَبِّكُمۡۚ أَفَلَا تَعۡقِلُونَ
And when they fall in with those who believe, they say: We believe. But when they go apart one with another they say: Prate ye to them of that which Allah hath disclosed to you that they may contend with you before your Lord concerning it? Have ye then no sense?
