وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَنَّحَدَّثَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ قَدْرُ حَوْضِي كَمَا بَيْنَ أَيْلَةَ وَصَنْعَاءَ مِنَ الْيَمَنِ وَإِنَّ فِيهِ مِنَ الأَبَارِيقِ كَعَدَدِ نُجُومِ السَّمَاءِ ‏"‏ ‏.‏
