Abu Musa Al-Ash'ari (May Allah be pleased with him) reported:
I asked the Messenger of Allah (ﷺ): "Who is the most excellent among the Muslims?" He said, "One from whose tongue and hands the other Muslims are secure." [Al-Bukhari and Muslim] .

"‏من سلم المسلمون من لسانه ويده‏"‏‏.‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏
