Raised in a question to challenge Islam on why people of the Gospel are told to judge by it if the text was supposedly unusable.

Quoted again to argue that Allah commands Christians to judge by the Gospel, implying the Gospel remained authoritative rather than corrupted beyond use.

Cited to argue that the Quran still directs Christians to judge by the Gospel, which the speaker presents as evidence against total textual corruption.

Brought up again to claim Christians are commanded to judge by the Gospel they have, not by a lost original only.

Repeated with 5:43 to argue that Christians are likewise sent back to the Gospel rather than away from it.
