Regarding the Hajj of the Prophet (ﷺ): He said, “Begin with what Allah had begun with” [ Reported by An-Nasa’i in this commanding version while Muslim has reported it in the reporting one].

وَعَنْ جَابِرٍ بْنِ عَبْدِ اَللَّهِ رَضِيَ اَللَّهُ عَنْهُمَا ‏-فِي صِفَةِ حَجِّ اَلنَّبِيِّ صَلَّى اَللَّهُ عَلَيْهِ وَسَلَّمَ‏- قَالَ ‏- صلى الله عليه وسلم ‏-{ اِبْدَؤُوا بِمَا بَدَأَ اَللَّهُ بِهِ } أَخْرَجَهُ النَّسَائِيُّ, هَكَذَا بِلَفْظِ اَلْأَمْر ِ [1]‏ وَهُوَ عِنْدَ مُسْلِمٍ بِلَفْظِ اَلْخَبَر ِ [2]‏ .‏
