وَأَنَّا ظَنَنَّا أَن لَّن تَقُولَ الْإِنسُ وَالْجِنُّ عَلَى اللَّهِ كَذِبًا (5)
(72:5) and that 'we had thought that men and jinn would never speak a lie about Allah', *6
*6) That is, "We were misled by those falsehoods because we could never think that the men or the jinn could ever dare forge a lie about Allah, but having heard this Qur'an we now know that they were, in fact, liars."
