Because He favors His servants, God the Blessed and Supreme gave them intellect, He gave them the power to refine and purify themselves, He sent the prophets and awliya [the friends of God, saints, holy men] to guide people and to help them to reform themselves so that they do not fall into the severe chastisement of hell.
