Musannaf Ibn Abi Shaybah

Hazrat Ubaid bin Abdul Malik narrates that the person who saw Hazrat Umar bin Abdul Aziz standing at the place of Arafat making this supplication told me. He was saying thus and was also gesturing with his finger. O Allah! Increase the goodness of the doers of good among the Ummah of Muhammad (peace and blessings be upon him), and turn their sinners towards repentance. Then he supplicated in this manner, and also moved his finger, and (said): And with Your mercy, encompass them from behind.
