Sayyiduna Jabir (may Allah be pleased with him) narrates: I asked, "O Messenger of Allah! Do we act regarding a matter that has already been decreed, or regarding a matter that is newly occurring?" The Prophet (peace and blessings be upon him) said: "It is a situation that has already been decreed." So Sayyiduna Jabir (may Allah be pleased with him) asked: "Then why should one act?" The Prophet (peace and blessings be upon him) said: "For every doer, his specific action has been made easy."
