The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, informed me from Abu al-Qasim Jaʿfar ibn Muhammad, from Muhammad ibn Yaʿqub, from several of our companions, from Ahmad ibn Muhammad and Abu Dawud together, from al-Husayn ibn Saʿid, from Fadalah ibn Ayyub, from al-Husayn ibn ʿUthman, from Samaah, from Abu Basir, from Abu Abdullah عليه السلام, who said: Imam عليه السلام said: "If you perform part of your Wuduʾ, and something interrupts you until your Wuduʾ dries, repeat your Wuduʾ, for Wuduʾ cannot be divided."
