وَإِذَا لَقُوا الَّذِينَ آمَنُوا قَالُوا آمَنَّا وَإِذَا خَلَا بَعْضُهُمْ إِلَىٰ بَعْضٍ قَالُوا أَتُحَدِّثُونَهُم بِمَا فَتَحَ اللَّهُ عَلَيْكُمْ لِيُحَاجُّوكُم بِهِ عِندَ رَبِّكُمْ ۚ أَفَلَا تَعْقِلُونَ ٧٦

And (they have reached such a state that) when they meet the believers, they say: ‘We (too) have believed (in Muhammad [blessings and peace be upon him], like you),’ and when they are together in isolation, they say: ‘Do you tell them (the Muslims) that which Allah has unfolded to you (through the Torah in connection with the Prophethood and glory of the last of the Prophets, Muhammad, [blessings and peace be upon him]) so that they may use it in argument against you in the holy presence of your Lord? Do you not have (even this much) sense?’ (2:76)
