Al-Baqara · 2:76

وَاِذَا لَقُوا الَّذ۪ينَ اٰمَنُوا قَالُٓوا اٰمَنَّاۚ وَاِذَا خَلَا بَعْضُهُمْ اِلٰى بَعْضٍ قَالُٓوا اَتُحَدِّثُونَهُمْ بِمَا فَتَحَ اللّٰهُ عَلَيْكُمْ لِيُحَٓاجُّوكُمْ بِه۪ عِنْدَ رَبِّكُمْۜ اَفَلَا 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?’

Word-by-word analysis is only wired up for the demo verses (1:1 and 1:2) for now.
