Surah Ya-Sin / Verse 16

In response to the accusation of lying, the messengers appeal to God's knowledge. Rather than becoming drawn into a dispute over whether a human being can receive revelation, they firmly affirm the truth of their mission: the Lord who sent them knows that they speak truthfully, and this knowledge is sufficient for them.

The words “Our Lord knows” here carry a force close to an oath. The declaration inna ilaykum la-mursalun also contains both inna and an emphatic lam. These repeated forms of emphasis express the messengers' steadfastness in the face of the people's accusations.

A deeper point is that the messengers do not need the people's approval in order to establish their standing before God. They are not trying to gain personal importance or prestige by winning acceptance, nor do they seek private advantage from the people's belief. What matters is their faithfulness to the task entrusted to them by God.

This does not mean that the people's belief is unimportant. Rather, it shows that the messengers have not made others' acceptance into a means of personal profit or status.
