"Everyone Should Treat People With Respect"

"Because we like to be treated kindly,
We ought to treat people in the same way."
The First Sermon
In the Name of God, the Compassionate, the Merciful

Leniency means to be sensitive to the feelings of others, so as to convey your ideas to them in a kind and peaceful way that opens their hearts, and minds, without resorting to any harsh words that might turn them away or even become aggressive.

Similarly, when you deal with others, even within your own family, whether your wife children, or parents, you ought to respect their feelings and be kind to them, for this is the way that makes your ideas enter the mind of the others, and make them emotionally ready to be understanding and compassionate.

As for violence, which in this case might be demonstrated by cursing the other, or the of use harsh words that drives him to feel that you are despising or challenging him, or talking to him in a conceited manner that humiliates him, just because you feel that you are in a position of power...

This idea, the need to be kind in your relations with others, whether at home, at work or in any other social dealing has been asserted in several verses in the Glorious Quran. We read" say to My servants that they speak that which is best". If you want to speak to others say the best worlds word, that unite and not disperse words that endears them and not provoke hatred. Words that takes into consideration the intellectual level of those who are hearing them… Just as you choose the best house, the best clothes and the best food, you have to chose the best words for they are for more significant than food or clothes… They might make you enter in a war or drive you into a contict :surely the Shaitan sows dissensions among them; surely the Shaitan is an open enemy to man.

Goodly exhortation

If you want to engage in a dialogue with others, with whom you are of different religious political and social affiliations them , you should Call to the way of your Lord with wisdom and goodly exhortation, and have disputations with them in the best manner; surely your Lord best knows those who go astray from His path, and He knows best those who follow the right way.
Even with the people of the Book, we are commanded to adhere to this method of dialogue, Enemies too should be turned into friends through this manner (_And not alike are the good and the evil. Repel (evil) with what is best, when lo! He between whom and you was enmity would be as if he were a warm friend).

But there are those who are not ready to enter in a dialogue with you. They depended on the flexing their muscles in a show of force. That is why Allah has excluded those who are unjust among the People of the Book an asked us to treat them as they treat us {If then any one transgresses the prohibition against you transgress ye likewise against him}. This is also what Allah taught His prophet, Noah, to do when his people made fun of him.

If you ridicule us now we can look down on you with ridicule likewise.

As for those who would have a dialogue with you treat them with good exhortation. For Allah puts everything in its place.
