It is narrated from Sayyiduna Hisham bin Hakim (may Allah be pleased with him) that a man came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! Do we begin our deeds anew, or has the decree already been written? The Messenger of Allah (peace and blessings be upon him) said: "Allah Almighty brought forth the offspring of Adam (peace be upon him) from his back, then, making them bear witness over themselves, said: 'Am I not your Lord?' They said: 'Indeed, yes.' Then He placed them in the scale-pan and said: 'These are in Paradise and these are in Hell.' So for the people of Paradise the deeds of the people of Paradise have been made easy, and for the people of Hell the deeds of the people of Hell have been made easy."
