Musnad Abu Ya'la al-Mawsili 5:15

Abu Khaythama narrated to us, Yazid bin Harun narrated to us, Ibn Abi Dhi'b informed us, from Muslim bin Jundub, from al-Zubayr bin al-Awwam, who said: We used to pray with the Messenger of Allah, may Allah bless him and grant him peace, then we would hasten to the thickets, and we would find nothing but the places of our feet.
