Abu Hurayrah (may Allah be pleased with him) says: Abu Bakr (may Allah be pleased with him) sent me at Mina on the Day of Sacrifice to announce: "After this year no polytheist shall come for Hajj, and no one shall circumambulate the House naked." And the Day of the Greater Hajj is the Day of Sacrifice; and it is said that it was called the Greater Hajj because people call Umrah the Lesser Hajj. Abu Bakr (may Allah be pleased with him) had it announced that a polytheist who performed Hajj this year should not perform Hajj the following year with the Prophet (peace and blessings be upon him). And in the year of Abu Bakr's (may Allah be pleased with him) announcement, Allah Almighty revealed this verse: "O you who believe! The polytheists are impure, so let them not come near al-Masjid al-Haram after this year." [Surah al-Tawbah: 28]
