Human nature desires a society based on morals and manners which provides a stable and secure life leading to liberty and happiness for all people.

Muslims believe Prophet Muhammad had a character as a model for all humanity to follow. The Quran describes the Prophet as:

By an act of mercy from God, you O' Prophet were gentle in your dealings with them - had you been harsh, or hard-hearted, they would have dispersed and left you - so pardon them and ask forgiveness for them. Consult with them about matters, then, when you have decided on a course of action, put your trust in God: God loves those who put their trust in Him? Quran 3:159
