[15]. Muhammed, God's messenger, peace and blessings be upon him, said: “Righteousness is good character and manners, and sin is what disturbs your heart and you hate for people to find out about it.”
Striving for righteousness means having a relationship with Allāh defined by obedience to His will and being shaped to have good character, taking as a model and good example the messenger of God, the Prophet Muhammad, for Allāh has not called us to impurity, but to righteousness. Being righteous makes the believers set themselves apart from the evils of the world.
