[Machine] The Messenger of Allah ﷺ said, "You should use the saddle, for indeed, the earth folds at night." I found in the book of rituals that I had dictated from this book a narration from Ruwaim ibn Yazid al-Muqri, from Al-Layth, from Aqil, from Az-Zuhri, from Anas. I made an effort at that time to find a witness for it but I did not find one. "And this is his witness, if it is confirmed by Khalid ibn Yazid al-Umari." If it is confirmed by Khalid, then it is reliable.  

قَالَ رَسُولُ اللَّهِ ﷺ «عَلَيْكُمْ بِالدُّلْجَةِ فَإِنَّ الْأَرْضَ تُطْوَى بِاللَّيْلِ» قَدْ كُنْتُ أَمْلَيْتُ فِي كِتَابِ الْمَنَاسِكِ مِنْ هَذَا الْكِتَابِ حَدِيثَ رُوَيْمِ بْنِ يَزِيدَ الْمُقْرِئُ عَنِ اللَّيْثِ عَنْ عَقِيلٍ عَنِ الزُّهْرِيِّ عَنْ أَنَسٍ وَجَهِدْتُ إِذْ ذَاكَ أَنْ أَجِدَ لَهُ شَاهِدًا فَلَمْ أَجِدْ «وَهَذَا شَاهِدُهُ إِنْ سَلِمَ مِنْ خَالِدِ بْنِ يَزِيدَ الْعُمَرِيِّ» إن سلم من خالد فجيد
