Musnad Ahmad 535:13

Musa narrated to us, Layth ibn Sa'd narrated to us, from Yazid ibn Abi Habib, from Abdullah ibn al-Harith ibn Juz' al-Zubaydi, who said: I am the first person who heard the Prophet, may Allah bless him and grant him peace, say: "Let not one of you urinate while facing the Qibla." And I am the first person who narrated it to the people from him.
