Quran 4:82

Repeatedly cited because the Muslim guest used it as a test for divine origin ('if it were from other than Allah they would find many discrepancies'), and the panel argued that this is a faulty argument and even oddly allows for 'many' rather than zero contradictions.

Used as a falsification challenge, arguing that the absence of true contradiction proves the Quran is from Allah.

Used to invoke the Quran's own falsification test: if it were from other than Allah, it would contain contradictions. The host used this after claiming to show a contradiction.

Quoted as the Quran's own test for divine authorship—if contradictions are found, it is not from Allah—and then used to argue Islam fails by that standard.

This verse was cited as the Quran's challenge to find contradictions in it; the later discussion returned to this challenge when arguing that the Quran contradicts itself.
