'Abdullah bin 'Amr bin Al-'as (May Allah be pleased with them) reported:
Messenger of Allah ﷺ did not indulge in loose talk nor did he like to listen to it. He used to say, "The best of you is the best among you in conduct."

[Al-Bukhari and Muslim].

وعن عبد الله بن عمرو بن العاص رضي الله عنهما قال: لم يكن رسول الله ﷺ فاحشاً ولا متفحشاً. وكان يقول: “إن من خياركم أحسنكم أخلاقاً” ((متفق عليه)).
