"The Messenger of Allah ﷺ was sleeping upon a mat, then he stood, and the mat had left marks on his side. We said: 'O Messenger of Allah! We said: 'O Messenger of Allah! We could get a bed for you.' He said: 'What do I have to do with the world! I am not in the world but as a rider seeking shade under a tree, then he catches his breath and leaves it.'"

نَامَ رَسُولُ اللَّهِ ﷺ عَلَى حَصِيرٍ فَقَامَ وَقَدْ أَثَّرَ فِي جَنْبِهِ فَقُلْنَا يَا رَسُولَ اللَّهِ لَوِ اتَّخَذْنَا لَكَ وِطَاءً فَقَالَ مَا لِي وَمَا لِلدُّنْيَا مَا أَنَا فِي الدُّنْيَا إِلاَّ كَرَاكِبٍ اسْتَظَلَّ تَحْتَ شَجَرَةٍ ثُمَّ رَاحَ وَتَرَكَهَا قَالَ وَفِي الْبَابِ عَنْ عُمَرَ وَابْنِ عَبَّاسٍ

The Messenger of Allah ﷺ laid down upon a reed mat and it left marks on his side. When he woke up, I started wiping his side, and I said, "O Messenger of Allah, why do you not let us spread something on top of this mat for you?" The Prophet said, "What is the world to me? What am I to the world? Verily, the parable of myself and this world is that of a rider who seeks shade under a tree, then he moves on and leaves it behind."

اضْطَجَعَ رَسُولُ اللهِ ﷺ عَلَى حَصِيرٍ فَأَثَّرَ فِي جَنْبِهِ فَلَمَّا اسْتَيْقَظَ جَعَلْتُ أَمْسَحُ جَنْبَهُ فَقُلْتُ يَا رَسُولَ اللهِ أَلَا آذَنْتَنَا حَتَّى نَبْسُطَ لَكَ عَلَى الْحَصِيرِ شَيْئًا؟ فَقَالَ رَسُولُ اللهِ ﷺ: «مَا لِي وَلِلدُّنْيَا؟ مَا أَنَا وَالدُّنْيَا؟ إِنَّمَا مَثَلِي وَمَثَلُ الدُّنْيَا كَرَاكِبٍ ظَلَّ تَحْتَ شَجَرَةٍ ثُمَّ رَاحَ وَتَرَكَهَا.»
