«إن العبد ليتكلم بالكلمة ما يتبين فيها يزل بها في النار أبعد ما بين المشرق والمغرب»
The Prophet (peace and blessings be upon him) said:
"Indeed, a servant (thoughtlessly) utters a word whose consequences he does not reflect upon, and because of that one word he falls into the Fire of Hell a distance farther than that between the east and the west."
