وَعَنِ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ ﷺ نَامَ عَلَى حَصِيرٍ، فَقَامَ وَقَدْ أَثَّرَ فِي جَسَدِهِ، فَقَالَ ابْنُ مَسْعُودٍ: يَا رَسُولَ اللَّهِ! لَوْ أَمَرْتَنَا أَنْ نَبْسُطَ لَكَ وَنَعْمَلَ. فَقَالَ: «مَا لِي وَلِلدُّنْيَا، وَمَا أَنَا وَالدُّنْيَا إِلَّا كَرَاكِبٍ اسْتَظَلَّ تَحْتَ شَجَرَةٍ ثُمَّ رَاحَ وَتَرَكَهَا». (Reported by al-Tirmidhi and Ibn Majah)
Translation: Ibn Masʿud reports that the Prophet ﷺ slept on a mat that left marks on his body. Ibn Masʿud offered to arrange and prepare more comfortable bedding. The Prophet ﷺ replied, “What have I to do with the world? My relationship with it is like a rider resting in the shade of a tree and then moving on, leaving it behind.”
The teaching does not declare comfort unlawful. It illustrates the limited duration of worldly life and the need to keep worldly attachments in perspective.
