The Messenger of Allah ﷺ said, "Let none of you be prevented by fear of people from speaking the truth when he sees it."
حدثنا خلف بن الوليد حدثنا خالد عن الجريري عن أبي نضرة
قال رسول الله ﷺ ألا لا يمنعن أحدكم مخافة الناس أن يقول الحق إذا رآه
Its isnad is sahih. Khalid is Ibn Abdullah bin Abdul-Rahman bin Yazid Wasiti, a trustworthy and firmly reliable narrator, and the hadith has already appeared at 11194.
