Abu Hurairah Radiyallahu anhu narrates
that Nabi Sallallahu alaihi wasallam said:
A man speaks a word pleasing to Allah
Subhanahu wa Ta ala,
without considering it of any importance,
yet Allah Subhanahu wa Ta ala exalts him in rank for it.
And a man speaks a word displeasing to Allah,
without considering it of any importance,
due to which he falls into Hell.
{ Bukhari }
