It is narrated from Sayyiduna Imran bin Husayn (may Allah be pleased with him) that a man said: "O Messenger of Allah, have the people of Paradise been known from the people of Hell?" He (peace and blessings be upon him) said: "Yes." He said: "Then for what do those who act, act?" He (peace and blessings be upon him) said: "Act, for everyone is made easy for that for which he was created."
