Why - when you (O believers) heard of it - did the believing men and the believing women not think well about their own selves, and (why did they not) say, “This is a manifest lie”.
Had it not been for the grace of Allah upon you, and His mercy in this world and in the Hereafter, a severe punishment would have reached you for what you indulged in -
when you were welcoming it with your tongues, and were saying with your mouths something of which you had no knowledge, and were taking it as a trivial matter, while in the sight of Allah it was grave.
