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

When they meet the believers, they say, ‘We too believe.’ But when they are alone with each other they say, ‘How could you tell them about God’s revelation [to us]? They will be able to use it to argue against you before your Lord! Have you no sense?’
And when they (Jews) meet those who believe (Muslims), they say, "We believe", but when they meet one another in private, they say, "Shall you (Jews) tell them (Muslims) what Allâh has revealed to you [Jews, about the description and the qualities of Prophet Muhammad صلى الله عليه وسلم, that which are written in the Taurât (Torah)], that they (Muslims) may argue with you (Jews) about it before your Lord?" Have you (Jews) then no understanding?
