When was the Farewell Pilgrimage of our Prophet Muhammad, may Allah bless him and grant him peace?

The Farewell Pilgrimage took place in the tenth year of the Hijra. The verse, "This day I have perfected for you your religion," was revealed on a Friday, after Asr prayer, on the Day of Arafat during the Farewell Pilgrimage, while the Messenger of Allah, peace and blessings be upon him, was standing on Arafat atop his she-camel.
