Yahya related to me from Malik from Abdullah ibn Abi Bakr ibn Muhammad ibn Amr ibn Hazm that he heard that the Messenger of Allah ﷺ said about the flood-channels of Mahzur and Mudhaynib (in Madina), "Dam them systematically, so that the water is diverted into each property in turn up to ankle level, starting upstream."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ فِي سَيْلِ مَهْزُورٍ وَمُذَيْنِبٍ يُمْسَكُ حَتَّى الْكَعْبَيْنِ ثُمَّ يُرْسِلُ الأَعْلَى عَلَى الأَسْفَلِ
