Ibn ‘Abbas told that the Prophet used to say when making supplication, "My Lord, help me and do not give help against me; grant me victory and do not grant victory over me; plan on my behalf and do not plan against me; guide me and make right guidance easy for me; grant me victory over those who act wrongfully towards me. My Lord, make me grateful to Thee, mindful of Thee, full of fear towards Thee, devoted to Thy obedience, humble before Thee, earnest in supplication, and penitent. My Lord, accept my repentance, wash away my sin, answer my supplication, clearly establish my evidence, make true my tongue, guide my heart, and draw out the malice in my breast.”
Anas said that the Prophet's most frequent supplication was, "O God, bring us blessing in this world, blessing in the next, and guard us from the punishment of hell."
Abu Bakr said that God’s messenger mounted the pulpit, then wept and said, "Ask God for forgiveness and health, for after being granted certainty, one is given nothing better than health."
Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying this is a hasan tradition whose isnad is gharib.
Abu Malik al-Ashja‘i told on his father’s authority that when a man accepted Islam the Prophet instructed him in the prayer, then commanded him to make supplication with these words, “O God, forgive me, show mercy to me, guide me, grant me health, and grant me provision.”
