Musannaf Ibn Abi Shaybah 31413 — What is mentioned on seeking

Sayyiduna Shaddad bin Aws (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said to him: "Shall I not guide you to the chief of the prayers for forgiveness? Say these words: 'O Allah, You alone are my God. There is no god but You. You created me and I am Your servant. I fulfil Your promise and Your covenant to the extent of my strength. I seek refuge in You from the evil of the deeds I have done. I acknowledge Your favours upon me, and I acknowledge my sins before You, so forgive me, for indeed none but You can forgive sins.' There is no servant who says these words in the day and his appointed time comes to him before evening, or says them in the evening and death comes before morning, except that he will be among the people of Paradise."
