Abu Dawud Book 36, Hadith Number 5068.

Narated By AbuDharr : If anyone says in the morning: “O Allah! whatever oath I take, whatever word I speak, and whatever vow I take, Thine will precedes all that: whatever Thou willeth, occurs, and whatever Thou dost not will, dost not occur. O Allah! pardon me and disregard me for it. O Allah! whomsoever Thou sendest thine blessing, to him my blessing is due, and whomsoever thou cursest, to him my curse is due, ” exemption from it will be granted to him that day.
