Musannaf Ibn Abi Shayba 33:617

Ibn Mahdi narrated to us, from Sufyan, from his father, from Abu Ya’la, who said: Rabi’ said: I do not like a servant’s pleading with his Lord, saying: "O Lord, You have decreed mercy upon Yourself; You have decreed such and such upon Yourself," as if he is finding it slow. And I have not seen anyone say: "O Lord, I have fulfilled what is upon me, so fulfill what is upon You."
