Mishkat al-Masabih #2320

Ibn ‘Umar said that when God’s messenger returned from an expedition, a hajj, or an ‘umra, on every rising piece of ground he would say three times, "God is most great." Then he would say, “There is no god but God alone who has no partner, to whom the dominion belongs, to whom praise is due, and who is omnipotent. We are returning repentant, serving, prostrating ourselves before our Lord, and expressing praise. God alone has verified His promise, helped His servant, and routed the Confederates.”* *The reference is to the siege of Medina in 5 A.H. when a trench was dug as a protection. (Bukhari and Muslim.)
