It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: None of you should let the fear of people prevent him from speaking the truth when he is present at the occasion or knows the truth. Sayyiduna Abu Sa'id (may Allah be pleased with him) says: This hadith encouraged me, so I mounted my ride and went to Sayyiduna Mu'awiyah (may Allah be pleased with him), narrated many ahadith to him, and then returned.
