وَقَٰرُونَ وَفِرْعَوْنَ وَهَٰمَٰنَ ۖ وَلَقَدْ جَآءَهُم مُّوسَىٰ بِٱلْبَيِّنَٰتِ فَٱسْتَكْبَرُوا۟ فِى ٱلْأَرْضِ وَمَا كَانُوا۟ سَٰبِقِينَ
And Korah, Pharaoh and Haman! Moses came unto them with clear proofs (of Allah's Sovereignty), but they were boastful in the land. And they were not winners (in the race).

Narrated Abu Huraira:
On the Day of Nahr (10th of Dhul-Hijja, in the year prior to the last Hajj of the Prophet (ﷺ) when Abu Bakr was the leader of the pilgrims in that Hajj) Abu Bakr sent me along with other announcers to Mina to make a public announcement: "No pagan is allowed to perform Hajj after this year and no naked person is allowed to perform the Tawaf around the Ka`ba. Then Allah's Messenger (ﷺ) sent `Ali to read out the Surat Bara'a (at-Tauba) to the people; so he made the announcement along with us on the day of Nahr in Mina: "No pagan is allowed to perform Hajj after this year and no naked person is allowed to perform the Tawaf around the Ka`ba."
