Musannaf Ibn Abi Shaybah 31489 — What is mentioned from Abu Bakr

Al-Rabi' said concerning Sayyiduna Umar (may Allah be pleased with him) that he used to supplicate thus: O Allah, I ask You to forgive my sins, I seek Your guidance to what is right in my affairs, and I repent to You, so accept my repentance; surely You alone are my Lord. O Allah, put in me a longing for You, put contentment in my breast, bless me in the provision You have given me, and accept my supplication from me; surely You alone are my Lord.
