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.
