Abdullah bin Umar reported,

Whenever the Prophet ﷺ returned from Hajj, Umra, or a military expedition, he would say "Allahu Akbar" three times upon every elevated place on the ground, then he would say, "There is no god but Allah alone, with no partner. To Him belongs the dominion, to Him belongs all praise, and He is capable of all things. We return, repenting, prostrating, worshipping our Lord and praising Him. Allah has fulfilled His promise, granted victory to His servant, and defeated the confederates alone."

Ahmad 5295

عن ابن عمر

أن النبي ﷺ كان إذا قفل من حج أو عمرة أو غزو كبر على كل شرف من الأرض ثلاثا ثم قال لا إله إلا الله وحده لا شريك له له الملك وله الحمد وهو على كل شيء قدير آيبون تائبون ساجدون عابدون لربنا حامدون صدق الله وعده ونصر عبده وهزم الأحزاب وحده
