Abu Bakr Leads the Hajj

The Prophet appointed Abu Bakr to lead 300 Muslims in the Hajj pilgrimage while he remained in Medina. After Abu Bakr departed, the opening verses of Surah at-Tawbah were revealed, declaring disassociation from the polytheists and giving them four months to accept Islam or leave the sacred precinct. The Prophet sent Ali ibn Abi Talib to catch up with Abu Bakr and announce these verses at Mina. From this year onward, no polytheist was permitted to perform Hajj or circumambulate the Ka'bah naked.
