Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Abu Uthman Nahdi that Hazrat Umar bin Khattab called for a razor so that he could cut the sleeve of Uqbah bin Farqad's shirt from his fingers. That person was wearing a very long shirt. Upon this, Uqbah said, "O Commander of the Faithful! Instead of you, I will do this myself. I feel shy that you cut it in front of people." Upon this, Hazrat Umar left him.
