Sayyiduna Ali (may Allah be pleased with him) said: O seekers of knowledge! Act upon it, for indeed the true scholar is the one who acts according to his knowledge, and whose knowledge and actions are in agreement. Soon there will be people who will carry knowledge, but that knowledge will not go below their throats. Their actions will be contrary to their knowledge, and their inner state will be different from their outward appearance. They sit in gatherings and boast to one another, so much so that if a man leaves his companion and sits with someone else, he becomes angry. These are the people whose deeds do not ascend from their gatherings to Allah Almighty.
