Musannaf Ibn Abi Shaybah 37572 — The words of Rabi bin Khuthaym

It is narrated from al-Rabi' that he said: I do not like the servant to make this supplication to his Lord, saying: O Allah, You have decreed mercy upon Yourself; You have decreed such-and-such upon Yourself, (saying this while) the servant regards the response as slow. And I have not seen anyone saying: O my Lord, I have fulfilled what was binding on me, so fulfil what is binding on You.
