There wasa cloth between his skin and the seat. 'Umar visited him and wept. TheProphet, may Allah bless him and grant him peace, said, 'What made youweep, 'Umar?' He said, 'By Allah, Messenger of Allah, I am only weepingsince I know that you are more noble with Allah than Chosroes and Caesar.They both live in what they live of this world while you, Messenger ofAllah, are in the place I see.' The Prophet, may Allah bless him and granthim peace, said, 'Are you not content, 'Umar, that they have this worldwhile we have the Next?' I replied, 'Yes, Messenger of Allah.' He said,'That is the way of it.'"
