ahAbu ‘Ubayd said: and regarding this there is an another interpretation which says: That it is regarding Hajj. ….From Mujāhid regarding His statement -the Most High- :
﴾ وَلَا جِدالِ فِي الْحَجِّ ﴿
{ and no disputing in Hajj } [Surah al Baqarah: 197]
He said: Hajj has been established in the month of Dhul Hijjah, and there should be no dispute in it.
And from Mujāhid, he said:The Arabs during Jāhiliyyah (time of ignorance) used to perform Hajj two years in Dhul Qi’dah and two years in Dhul Hijjah, so when it was the year wherein Abu Bakr performed Hajj before the Hajj of the Prophet ﷺ , Hajj was in the second year in Dhul Qi’dah, and when it was the year the Prophet ﷺ performed Hajj, the following year, Hajj returned to Dhul Hijjah.
And that is his (ﷺ)statement: Verily the time has revolved around in its original configuration the day Allah created the heavens and earth.¹
He says: Hajj has been establisted in Dhul Hijjah.
