Musnad Ahmad 27:1380

'Attab ibn Ziyad narrated to us, Abdullah—meaning Ibn al-Mubarak—narrated to us, Musa ibn 'Uqbah informed us, from Salim and Nafi', from Abdullah, that the Messenger of Allah (peace and blessings of Allah be upon him), when he would return from a military expedition, or Hajj, or 'Umrah, would begin by saying the takbir three times, then he would say: "There is no god but Allah alone, He has no partner. To Him belongs the dominion, and to Him belongs the praise, and He is capable of all things. We are returning, repenting, worshipping, prostrating to our Lord, praising. Allah fulfilled His promise, and aided His servant, and defeated the confederates alone." Ali ibn Ishaq narrated to us, Abdullah informed us, Musa ibn 'Uqbah informed us, from Salim and Nafi', from Abdullah, that the Messenger of Allah (peace and blessings of Allah be upon him) used to—and he mentioned the like of it.
