Islam is a good example. Character strength is a key ingredient in a Muslim. The virtues exalted by the Quran are the same humanitarian values that previous prophets, reformers, philosophers and other thinkers have always pushed for. Among the basic goals of religion is to protect man against the temptations of evil, by reeling its harm, warning against it, and calling its victims back to righteousness based on God's promise of good rewards to the righteous in the present world and the hereafter. To achieve that objective, religion uses high morals as one of the important vehicles.
Spiritual promotion goes hand in hand with upright behavior.
Evil deeds lead individuals and whole communities to personal and collective disaster. That is why God promises bounty and happiness to those who guide their spirits with his forgiveness and containment. God requests mankind to amend themselves, to be able to ensure their gifts in the hereafter. High morals are an important component in spiritual well-being because they enable the spirit to reign over the desires and excesses of the flesh. Self purification combines the cleanliness of one's heart with rising above disgrace so that one can attain a share of God's dignity and contentment.
