From Shaddaad ibn Aws from the Prophet (sallâ Allâhu 'alayhi wa sallam) that he said, "The noblest and most excellent manner of seeking forgiveness is that the servant says:

"O Allaah, You are my Lord. None has the right to be wrshipped except You. You created me, and I am Your slave/worshipper. And I am faithful to my covenant and my promise as far as I am able. I seek Your refuge from the evil of what I have done. I acknowledge before You all the favours that You have bestowed upon me. And I confess all my sins to You. So forgive me, since none can forgive sins except You."

The Prophet (sallâ Allâhu 'alayhi wa sallam) said, "Whoever says it in the day, with firm conviction in it, and dies in that day before evening - then he is from the people of Paradise. Whoever says it in the night, with firm conviction in it, and he dies before the Morning - then he is from the people of Paradise."
