Musannaf Ibn Abi Shaybah 31163 — The supplication on leaving one's

Sayyiduna Abu Sa'id (may Allah be pleased with him) said: "When a person goes out for prayer and recites this supplication: 'O Allah! I ask You by the right that those who ask have upon You, and by the right of this walking of mine. I have not gone out in arrogance, nor strutting, nor to show off, nor to gain fame. I have gone out only seeking Your pleasure and to avoid Your displeasure. And I ask You to save me from Hell and to forgive my sins; indeed, none besides You forgives sins.' Then Allah Almighty turns towards that servant with His Face until he returns, and Allah Almighty assigns seventy thousand angels who keep seeking forgiveness for that person."
