Musnad Ahmad 4636

Translation

✧ When the Messenger of Allah ﷺ returned from a military expedition, or Hajj, or Umrah, and ascended a high ground or an elevation, he would say: Allah is the greatest, Allah is the greatest. There is no god but Allah alone, with no partner. His is the dominion and His is the praise, and He is able to do all things. We are returning, repenting, prostrating, worshipping, praising our Lord. Allah has fulfilled His promise, aided His servant, and defeated the confederates alone.
