حَدَّثَنَا مَحْمُودُ بْنُ غَيْلانَ، قَالَ: حَدَّثَنَا أَبُو دَاوُدَ، عَنْ شُعْبَةَ، عَنِ الأَشْعَثِ بْنِ سُلَيْمٍ، قَالَ: سَمِعْتُ عَمَّتِي، تُحَدِّثُ عَنْ عَمِّهَا، قَالَ: بَيْنَا أَنَا أَمشِي بِالْمَدِينَةِ، إِذَا إِنْسَانٌ خَلْفِي يَقُولُ: ارْفَعْ إِزَارَكَ، فَإِنَّهُ أَتْقَى وَأَبْقَى فَإِذَا هُوَ رَسُولُ اللهِ صلى الله عليه وسلم، فَقُلْتُ: يَا رَسُولَ اللهِ إِنَّمَا هِيَ بُرْدَةٌ مَلْحَاءُ، قَالَ: أَمَا لَكَ فِيَّ أُسْوَةٌ؟ فَنَظَرْتُ فَإِذَا إِزَارُهُ إِلَى نِصْفِ سَاقَيْهِ.
Al-Ash'ath ibn Sulaim said:
"I heard my maternal aunt relate, on the authority of her paternal uncle; 'While I was walking in Medina, someone behind me said: ‘Raise your loincloth, for that is more pious and conducive to longer wear.’ Lo and behold, he was Allah’s Messenger (Allah bless him and give him peace)', so I said: ‘O Messenger of Allah, it is simply a black garment with white stripes!’ He said: ‘Do you not have an example in me?’ so I looked and noticed that his loincloth was to half his shins'.”
