'A'isha reported: When the Messenger of Allah ﷺ pronounced salutation, he salutation longer than it took him to say: O Allah: Thou art Peace, and peace comes from Thee, blessed art Thou, Possessor of Glory and Honour; and in the narration of Ibn Numair the words are:" O Possessor of Glory and Honour".
The values taught in this hadith are faithfulness towards God, humility before Him, gratitude for His blessings, remembrance of Him at all times, seeking refuge in Him during difficult times etc. It also teaches us to be kind towards others by wishing them peace from God's side too.
