Musannaf Ibn Abi Shaybah 36996 — The words of Sulayman bin Dawud

Thabit al-Bunani said: It has reached us that the Prophet Dawud (peace be upon him) had apportioned the prayer among his households, among his wives and children. Whether it was any moment of the day or any part of the night, at all times someone from his family would be occupied in prayer. So this verse applies generally to all of them (of his family, who took part in this good deed): O family of Dawud, give thanks (to your Lord), and few of My servants are (truly) thankful.
