حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ‏:‏ حَدَّثَنَا أَبُو دَاوُدَ الطَّيَالِسِيُّ، قَالَ‏:‏ حَدَّثَنَا هَمَّامٌ، عَنْ، قَالَ‏:‏ قُلْتُ لأَنَسِ بْنِ مَالِكٍ‏:‏ كَيْفَ كَانَ نَعْلُ رَسُولِ اللهِ صلى الله عليه وسلم‏؟‏ قَالَ‏:‏ لَهُمَا قِبَالانِ‏.‏

'Ubaid ibn Juraij said to Ibn 'Umar

"I saw you wearing the tanned ox-hide sandals with no hair on them [an-ni'al as-sibtiyya]." He replied:"I saw Allah’s Messenger (Allah bless him and give him peace) wearing the sandals on which there is no hair, and he performed the minor ritual ablution in them, so I love to wear them!”
