What is the ruling on supplicating with the words: "O Allah, grant us repentance so that we may repent"?

There is no impediment to supplicating with the phrase, "O Allah, turn to us so that we may repent," for the repentance of a servant is preceded by Allah's enabling him, in accordance with His, the Almighty's, saying: "Then He turned to them that they might repent." It is also recommended to frequently use the formulas of seeking forgiveness that are authentically transmitted in the Sunnah.
