Musannaf Ibn Abi Shayba 33:1086

Jarir narrated to us, from 'Umarah ibn al-Qa'qa', from al-Hasan, regarding His saying: "So let him not drive you both out of Paradise, so that you suffer," he said: He meant by it the suffering of the world. So you will not meet a son of Adam except that he is suffering and struggling.
