And the explanation that the Prophet Muhammad (peace be upon him) performed Hajj even before the migration to Madinah. Contrary to the opinion of that scholar who criticized the authenticity of this hadith and claimed that only Zaid bin Hubab narrates this hadith (and he is weak in narrating from Imam Thawri).

Sayyiduna Jubair bin Mut’im (may Allah be pleased with him) narrates that I saw the Messenger of Allah (peace and blessings be upon him) before revelation came to him, that he was standing on his camel with the people in the plain of Arafat. He returned from the plain of Arafat along with them. And this action of his was purely by the guidance of Allah Almighty (because the Quraysh, considering themselves the standard-bearers of the religion, would not go outside the boundaries of the Haram). Imam Abu Bakr (may Allah have mercy on him) says that their statement“before revelation came to him”— it is possible that by this is meant before the revelation of this verse «‏‏‏‏ثُمَّ أَفِيضُوا مِنْ حَيْثُ أَفَاضَ النَّاسُ» ‏‏‏‏ [ سورة البقرة: 199 ] “Then depart from where the people depart,”or it is also possible that by this is meant that before the complete Qur’an was revealed (and before you were appointed as a Prophet), I saw you in the plain of Arafat. And the evidence for the correctness of this interpretation is the following hadith.
