Musannaf Ibn Abi Shaybah

Hazrat Rabi’ narrates regarding Hazrat Umar that he used to supplicate as follows: O Allah! I seek forgiveness from You for my sins. And I seek guidance from You for my good deeds. And I repent to You. So please accept my repentance. Surely, You alone are my Lord. O Allah! Instill in me longing for You. And place contentment in my heart. And bless the sustenance You have granted me. And accept my supplication on my behalf. And surely, You alone are my Lord.
