Musannaf Ibn Abi Shaybah

Hazrat Silah bin Zufar narrates that I heard Hazrat Abdullah bin Umar (may Allah be pleased with them) say these words after the prayer: "O Allah! You are the Source of peace, and from You is peace. You are blessed, O Possessor of Majesty and Honor." Then I performed prayer beside Hazrat Abdullah bin Amr (may Allah be pleased with him) and heard him say the same words. So I said to him: I have also heard Hazrat Ibn Umar (may Allah be pleased with them) say the same words that you have recited. Hazrat Abdullah bin Amr (may Allah be pleased with him) replied: Indeed, I heard the Messenger of Allah (peace and blessings be upon him) recite these words at the end of the prayer.
