Sayyiduna Abu Qursafah Jundarah bin Khayshanah Laithi (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) said: "May Allah keep fresh and flourishing the person who hears my words, remembers them, and preserves them. Many carriers of knowledge convey it to those who have more understanding than themselves. There are three things regarding which the heart should not be treacherous: sincerity in action for Allah, goodwill towards the rulers, and adhering to the community."
