Injil ‘sent down’?

“The Qur’ān describes the Injīl as something “sent down”; but the present-day Injīl was written by Jesus’ followers”

The Arabic term ‘sent down’ does not mean dropped from the sky or delivered by a prophet. It has a more general meaning of a gift from God. The same term “sent down” is used of the resource iron in 57:25: “We have sent down iron, with its mighty strength and diverse uses for mankind, so that God may recognize those who aid Him..”
