The Cow - 2:263 A kind word and forbearance is better than charity which is followed by dishonorable treatment. Allah is Rich, Compassionate.
To what does Allah liken a beautiful word?
Prophet Abraham/14:24 Do you not see that Allah likens a good word to a beautiful tree: Its root is fixed and its branches are in the sky.
Prophet Abraham/14:25 It yields its fruit in every season by the permission of your Lord. Allah gives such examples to mankind that they may take admonition.

Originator/35:10 Those who desire honor, know that all honor belongs to Allah. The good word ascends to Him, and the good deed elevates Him. For those who plot evil there is a severe torment and their plans will fail.
