Musannaf Ibn Abi Shaybah 37212 — The words of Umar bin al-Khattab

It is narrated from a man named Mika'il that he said: When Sayyiduna Umar (may Allah be pleased with him) stood in prayer at night, he would say: "You see where I stand and You know my need. So, O Allah, send me back from Your presence with my need, successful and with my supplication answered, You having forgiven me and shown me mercy." And when Sayyiduna Umar (may Allah be pleased with him) finished his prayer, he would say: "O Allah! I see nothing of this world lasting, and I see no state in it remaining steady. O Allah! Make me one who speaks in this world with knowledge and keeps silent in it with wisdom. O Allah! Do not give me so much of this world that I become rebellious, nor so little of it that I forget. For indeed, a small amount of this world that suffices is better than a large amount that distracts."
