Abdullah ibn Amr reported: It was said to the Messenger of Allah, “Which of the people is best?” The Messenger of Allah, peace and blessings be upon him, said, “Everyone who is pure of heart and truthful in speech.” They said, “Truthful in speech we know, but what is a pure heart?” The Prophet said, “It is a heart that fears Allah and is clean. There is no sin in it and neither aggression, malice, or envy. ”
