Musannaf Ibn Abi Shayba 1:1609

Shababa narrated to us, he said: Layth ibn Sa'd narrated to us, from Yazid ibn Abi Habib, that he heard Abdullah ibn al-Harith al-Zubaydi saying: I am the first one who heard the Messenger of Allah (ﷺ) while he was saying: "Let not one of you urinate while facing the Qibla." And I am the first one who narrated it to the people.
