From Sahih Muslim (Hadith 1346):
Abu Zubair al-Makki reported that he had heard 'Abdullah b. Zubair uttering (the words) like that of the hadith (narrated above) at the end of the prayer after pronouncing salutation. He at the conclusion also said that he was making a mention of that from the Messenger of Allah (ﷺ)
