Surah Al-Jinn — Ayah 5 (72:5)
وَأَنَّا ظَنَنَّآ أَن لَّن تَقُولَ ٱلۡإِنسُ وَٱلۡجِنُّ عَلَى ٱللَّهِ كَذِبٗا ٥
English translation (Saheeh International)
And we had thought that mankind and the jinn would never speak about Allāh a lie.
Brief commentary
And that we thought that the idolaters from among mankind and the jinn were not speaking lies when they claimed that He had a wife and child, so we accepted their statement blindly following them.
