Musannaf Ibn Abi Shaybah 31234 — What is said after the prayers

Al-Rabi' said: When Sayyiduna Umar (may Allah be pleased with him) finished his prayer, he would supplicate like this: "O Allah, I seek Your forgiveness for my sins, I seek Your guidance towards the right course in my affairs, and I turn to You in repentance, so accept my repentance. O Allah, You are my Lord, so make my longing be for You, grant me in my breast freedom from need of anyone but You, bless me in what You have provided me, and accept my supplication; indeed You are my Lord."
