Musannaf Ibn Abi Shaybah 4738 — Lightening the prayer: those who used

Abu Raja' said: I saw Sayyiduna al-Zubayr bin al-Awwam (may Allah be pleased with him) offer a very short prayer. I said to him: "You are Companions of the Messenger of Allah (peace and blessings be upon him), and yet you pray so briefly?" Sayyiduna al-Zubayr said: "We want to ward off these whisperings."
