[The characteristics of the virtuous whose guidance must be followed :] Know that, certainly, those creatures of Allāh who preserve His knowledge offer protection to those things which He desires to be protected and make His springs flow (for the benefit of others). They contact each other with friendliness and meet each other with affection. They drink water from cups that quench the thirst and return from the watering places fully satiated. Misgiving does not affect them and backbiting does not gain ground with them. In this way Allāh has tied their nature with good manners. Because of this they love each other and meet each other. They have become superior, like seeds which are selected by taking some and throwing away others. This selection has distinguished them and the process of choosing has purified them.
