Abdullah bin Umar reported,

Whenever the Messenger of Allah ﷺ returned from a military campaign, from Hajj, or from the lesser pilgrimage, he would say "Allah is greatest" three times upon every high point of ground, and then he would say, "There is no god but Allah alone, He has no partner. His is the dominion and His is the praise, and He has power over all things. We return, repenting, worshipping, prostrating to our Lord, and praising Him. Allah has fulfilled His promise, granted victory to His servant, and defeated the confederates alone."

و حدثني عن مالك عن نافع

عن عبد الله بن عمر

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