باب إِثْبَاتِ حَوْضِ نَبِيِّنَا صلى الله عليه وسلم وَصِفَاتِهِ ‏‏
Sahih Muslim 2299 c

A hadith like this has been transmitted on the authority, of 'Ubaidullah with this addition:

Ubaidullah was asked (about these two names, i. e. Jarba' and Adhruh). He said: These are the two towns of Syria and there is between them the distance which can be covered in three nights, and the hadith transmitted on the authority of Ibn Bishr (the words are)." Three days."
وَحَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبِي ح، وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ، بِشْرٍ قَالاَ حَدَّثَنَا عُبَيْدُ اللَّهِ، بِهَذَا الإِسْنَادِ ‏.‏ مِثْلَهُ وَزَادَ قَالَ عُبَيْدُ اللَّهِ فَسَأَلْتُهُ فَقَالَ قَرْيَتَيْنِ بِالشَّامِ بَيْنَهُمَا مَسِيرَةُ ثَلاَثِ لَيَالٍ ‏.‏ وَفِي حَدِيثِ ابْنِ بِشْرٍ ‏.‏ ثَلاَثَةِ أَيَّامٍ ‏.‏
