Surah An-Nur — Ayah 53 (24:53)

English translation (Saheeh International)

And they swear by Allāh their strongest oaths that if you ordered them, they would go forth [in Allāh's cause]. Say, "Do not swear. [Such] obedience is known.¹ Indeed, Allāh is [fully] Aware of that which you do."

1. - i.e., the hypocrites' pretense of obedience is known to be a lie.

Brief commentary

The hypocrites take the strongest and far-fetched of oaths possible upon Allah, saying that if you were to command them to march out to jihad, they would indeed do so. O Messenger! Say to them: “Do not take oaths, for your lying is well known, as is your claimed submission. Allah is well-aware of your actions; no action of yours is hidden from Him, regardless of how you try to hide them.
