9- حَدَّثَنا أَبُو عَلِيٍّ مُحَمَّد بن أَحمَد المعاذي قالَ سَمِعتُ أباالنصر المُوَدَّب يَقُولُ: امْتَلا السَّيْلُ يَوْماً سَنَابَادَ وَكَانَ الْوَادِي أَعْلَى مِنَ الْمَشْهَدِ فَأَقْبَلَ السَّيْلُ حَتَّى إِذَا قَرُبَ مِنَ الْمَشْهَدِ خِفْنَا عَلَى الْمَشْهَدِ مِنْهُ فَارْتَفَعَ بِإِذْنِ اللَّهِ وَقُدْرَتِهِ عَزَّ وَجَلَّ وَوَقَعَ فِي قَنَاةٍ أَعْلَى مِنَ الْوَادِي وَلَمْ يَقَعْ فِي الْمَشْهَدِ مِنْهُ شَيْءٌ.

69-9 Abu Ali Muhammad ibn Ahmad al-Mo’athi narrated that he had heard Abal Nasr al-Mo’aththin say, “One day a great flood flowed in Sanabad where there is a valley higher than the Shrine. The flood directed itself towards the Shrine and it was feared that it would reach the Shrine. Then by God’s permission, the threat was removed and (opposite to the laws of nature) the flood went into a waterway that was higher than the valley; and no damage was done to the Shrine.
