Musnad Ahmad 190:0

Narrated Bilal bin al-Harith al-Muzani: The Messenger of Allah (ﷺ) said: "Indeed, a man may speak a word of the pleasure of Allah, not realizing how far it reaches, yet Allah records for him His pleasure until the day he meets Him. And a man may speak a word of the wrath of Allah, not realizing how far it reaches, yet Allah records for him His wrath until the day he meets Him."
