Sayyiduna Thawban (may Allah be pleased with him) narrates: When the Prophet (peace and blessings be upon him) intended to stand up after the prayer, he would recite Istighfar three times, then he would recite this supplication: "O Allah! You are the Giver of peace. Peace can only be obtained from You. O Possessor of Majesty and Honor, You are Blessed."
