[Machine] I entered upon the Messenger of Allah who was in a room like a bathroom, and he was sleeping on a mat that left marks on his side. So, I cried, and he said, "What makes you cry, O Abdullah?" I said, "O Messenger of Allah, the Kisra and the Caesar tread on silk and brocade, while you are sleeping on this mat that has left marks on your side." He said, "Do not cry, O Abdullah, for they have the worldly life, and we have the Hereafter. And what is the relationship between me and the worldly life? My example and the example of worldly life is like a rider who stays under a tree, then moves on and leaves it."  

دَخَلْتُ عَلَى رَسُولِ اللهِ ﷺ وَهُوَ فِي غُرْفَةٍ كَأَنَّهَا بَيْتُ حَمَامٍ وَهُوَ نَائِمٌ عَلَى حَصِيرٍ قَدْ أَثَّرَ بِجَنْبِهِ فَبَكَيْتُ فَقَالَ «مَا يُبْكِيكَ يَا عَبْدَ اللهِ؟» قُلْتُ يَا رَسُولَ اللهِ كِسْرَى وَقَيْصَرُ يَطَئُونَ عَلَى الْخَزِّ وَالْحَرِيرِ وَالدِّيبَاجِ وَأَنْتَ نَائِمٌ عَلَى هَذَا الْحَصِيرِ قَدْ أَثَّرَ بِجِنْبِكَ قَالَ «فَلَا تَبْكِ يَا عَبْدَ اللهِ؛ فَإِنَّ لَهُمُ الدُّنْيَا وَلَنَا الْآخِرَةَ وَمَا أَنَا وَالدُّنْيَا وَمَا مَثَلِي وَمَثَلُ الدُّنْيَا إِلَّا كَمَثَلِ رَاكِبٍ نَزَلَ تَحْتَ شَجَرَةٍ ثُمَّ سَارَ وَتَرَكَهَا»
