An-Nur 24:15

Ith talaqqawnahu bi-alsinatikumwataqooloona bi-afwahikum ma laysa lakum bihiAAilmun watahsaboonahu hayyinan wahuwa AAinda AllahiAAatheem

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 Allāh, tremendous.

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.
