1. We were told by Muhammed bin Ahmad al-Sinani, may Allah be pleased with him, that he said: We were told by Muhammed bin Abi Abdillah al-Kufi, from Musa bin Imran al-Nakha’i, from his paternal uncle, Hussain bin Yazid al-Nawfali, from Muhammed bin Hamran, from his father, from Abu Khalid al-Kabuli, that he said: It was said to Ali bin Hussain, peace be upon them both: Where do the estranged perform Wudu? He said: They should be warned from the shores from rivers, leading roads, under fruitful trees and the spots of curse. It was said to him: And what are the spots of curse? He said: The doors of houses.
