Al Baqarah, 76 Ayah
2:76
وَإِذَا لَقُواْ ٱلَّذِينَ ءَامَنُواْ قَالُوٓاْ ءَامَنَّا وَإِذَا خَلَا بَعۡضُهُمۡ إِلَىٰ بَعۡضٖ قَالُوٓاْ أَتُحَدِّثُونَهُم بِمَا فَتَحَ ٱللَّهُ عَلَيۡكُمۡ لِيُحَآجُّوكُم بِهِۦ عِندَ رَبِّكُمۡۚ أَفَلَا تَعۡقِلُونَ ٧٦
Wa 'Idhā Laqū Al-Ladhīna 'Āmanū Qālū 'Āmannā Wa 'Idhā Khalā Ba`đuhum 'Ilá Ba`đin Qālū 'Atuĥaddithūnahum Bimā Fataĥa Al-Lahu `Alaykum Liyuĥājjūkum Bihi `Inda Rabbikum ۚ 'Afalā Ta`qilūna
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?
