Translation of the verse 15 from Surah An-Nur : Number of verses 64 - - page 351 - Part 18.
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 Allah it was very great.
When you received it with your tongues and said with your mouths that of which you had no knowledge and thought it was insignificant while it was, in the sight of Allah, tremendous.
(24:15) (Just think how erroneous you were,) when you passed this lie on from one tongue to the other and uttered with your mouths that of which you had no knowledge. You took it as a trifling matter whereas it was a grave offence in the sight of Allah.
