An-Noor 24:15

when you were passing it from one tongue[10] to the other, and saying with your mouths what you had no knowledge of, and were taking it lightly, whereas with Allah it was a grave offense.

[10] Rather than your ears, i.e., not thinking about what you hear but hastening to pass it on to others without verifying it.

When you received it with your tongues[980] and said with your mouths that of which you had no knowledge and thought it was insignificant while it was, in the sight of Allāh, tremendous.

[980] Rather than your ears, i.e., not thinking about what you had heard but hastening to repeat it carelessly.

15. When you were propagating it with your tongues, and uttering with your mouths that whereof you had no knowledge, you counted it a little thing, while with Allâh it was very great.

When ye welcomed it with your tongues, and uttered with your mouths that whereof ye had no knowledge, ye counted it a trifle. In the sight of Allah it is very great.
