Musannaf Ibn Abi Shayba 3:2289

Abdah narrated to us, from Ibn Abi Arubah, from Abu Raja, who said: I saw al-Zubayr ibn al-Awwam perform a light prayer. I said: "You, the companions of the Messenger of Allah (may Allah bless him and grant him peace), are the lightest of people in prayer." He said: "We are hastening away from this whisper (waswas)."
