Abu Dawud Book 36, Hadith Number 5056.

Chapter : Not known.

Narated By Abdullah ibn Umar : The Apostle of Allah (PBUH) never failed to utter these supplications in the evening and in the morning: O Allah, I ask Thee for security in this world and in the Hereafter: O Allah! I ask Thee for forgiveness and security in my religion and my worldly affairs, in my family and my property; O Allah! conceal my fault or faults (according to Uthman’s version), and keep me safe from the things which I fear; O Allah! guard me in front of me and behind me, on my right hand and on my left, and from above me: and I seek in Thy greatness from receiving unexpected harm from below me.” AbuDawud said: Waki’ said: That is to say, swallowing by the earth.
