Musannaf Ibn Abi Shaybah 34591 — Reports on refraining from speaking

Qabisah bin Jabir (may Allah have mercy on him) said: Sayyiduna Umar (may Allah be pleased with him) stood at the gate of al-Jabiyah and addressed us, saying: "Indeed, the Messenger of Allah (peace and blessings be upon him) stood among us just as I stand among you today. Then he (peace and blessings be upon him) said: 'O people! Fear Allah regarding my Companions (may Allah be pleased with them), then regarding those joined to them, and then regarding those joined to them as well. Then lying and false testimony will spread.'"
