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.
He said that when the Prophet was on a journey he would say at daybreak, "Let a hearer hear beginning with praise of God and His good favour towards us. Our Lord, accompany us and show favour to us who are seeking refuge in God from hell."
‘Abdallah b. Abu Aufa said that God’s messenger invoked a curse on the polytheists at the battle of the Confederates, saying, “O God, who hast sent down the Book and art quick to take reckoning; O God, rout the Confederates, rout them and convulse them.”
Abu Huraira told of a man coming to God’s messenger and saying, “Messenger of God, what I have suffered from a scorpion which stung me last night!” He replied that if he had said in the evening, "I seek refuge in God’s perfect words from the evil of what He has created," it would not have harmed him.
