Surah Ibrahim, Verse 26

وَمَثَلُ كَلِمَةٍ خَبِيثَةٖ كَشَجَرَةٍ خَبِيثَةٍ ٱجۡتُثَّتۡ مِن فَوۡقِ ٱلۡأَرۡضِ مَا لَهَا مِن قَرَارٖ٢٦

wamathalu kalimatin khabīthatin kashajaratin khabīthatin uj'tuthat min fawqi l-arḍi mā lahā min qarārin

And the example of a bad word is like a bad tree, uprooted from the surface of the earth, not having any stability.
