[Machine] Umar ibn Al-Khattab entered upon the Prophet ﷺ while he was on a mat that had left an impression on his side. Umar said, "O Messenger of Allah, if you were to take a softer mattress than this?" He replied, "O Umar, what do I have to do with this world? And what does this world have to do with me? By the One in Whose Hand is my soul, my example and the example of this world is like that of a traveler who walked on a hot day and took shade under a tree for an hour during the day, then left it."
دَخَلَ عُمَرُ بْنُ الْخَطَّابِ عَلَى النَّبِيِّ ﷺ وَهُوَ عَلَى حَصِيرٍ قَدْ أَثَرَ فِي جَنْبِهِ فَقَالَ يَا رَسُولَ اللَّهِ لَوِ اتَّخَذْتَ فِرَاشًا أَوْثَرَ مِنْ هَذَا؟ فَقَالَ «يَا عُمَرُ مَا لِي وَلِلدُّنْيَا وَمَا لِلدُّنْيَا وَلِي وَالَّذِي نَفْسِي بِيَدِهِ مَا مَثَلِي وَمَثَلُ الدُّنْيَا إِلَّا كَرَاكِبٍ سَارَ فِي يَوْمٍ صَائِفٍ فَاسْتَظَلَّ تَحْتَ شَجَرَةٍ سَاعَةً مِنْ نَهَارٍ ثُمَّ رَاحَ وَتَرْكَهَا»
