(15)Chapter: Something Else: ‘The Chief Of Supplications For Forgiveness’
Shaddad bin Aws narrated that:
The Prophet said to him: “Should I not direct you to the chief of supplications for forgiveness? ‘O Allah, You are my Lord, there is none worthy of worship except You, You created me and I am Your slave. I am adhering to Your covenant and Your promise as much as I am able to, I seek refuge in You from the evil of what I have done. I admit to You your blessings upon me, and I admit to me sins. So forgive me, for there is none who can forgive sins except You (Allahumma Anta Rabbi La Ilaha Illa Anta Khalaqtani Wa Ana `Abduka Wa Ana `Ala `Ahdika Wa Wa’dika Ma-stata’tu. A’udhu Bika Min Sharri Ma Sana’tu Wa Abu'u ilayka Bini’matika Alayya Wa A’tarifu Bidhunubi Faghfirli Dhunubi Innahu La Yaghfirudh-Dhun

uba Illa Ant).’ None of you says it when he reaches the evening, and a decree comes upon him before he reaches morning, except that Paradise becomes obligatory upon him. And none says it when he reaches the morning, and a decree comes upon him before he reaches evening, except that Paradise becomes obligatory for him.”
