Musannaf Ibn Abi Shaybah 31884 — What a man says in supplication

Qays bin Abbad says that Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said: "Whoever, on finishing his ablution, recites these words: 'You are free of all imperfection, O Allah, and all praise is Yours. I bear witness that there is no true deity except You. I ask You for forgiveness and I turn to You in repentance,' a seal is placed upon these words, and they are raised up to beneath the Throne, and it will not be broken until the Day of Resurrection."
