I came upon Messenger of Allah ﷺ when he was at Al-Batha. He asked me, "Have you intended to perform the Hajj?" I replied in the affirmative. He asked, "For what have you assumed lhram?" I replied," I have assumed Ihram with the same intention as that of the Prophet ﷺ ." The Prophet ﷺ said, "You have done well! Go and perform Tawaf round the Kaʿba and between Safa and Marwa." Then I went to one of the women of Bani Qais and she took out lice from my head. Later, I assumed the Ihram for Hajj. So, I used to give this verdict to the people till the caliphate of ʿUmar. When I told him about it, he said, "If we take (follow) the Holy Book, then it orders us to complete Hajj and ʿUmra (Hajj-at- Tamattuʿ) and if we follow the tradition of Messenger of Allah ﷺ then Messenger of Allah ﷺ did not finish his lhram till the Hadi had reached its destination (had been slaughtered). (i.e. Hajj-al-Qiran). (See Hadith No. 630)  

قَدِمْتُ عَلَى رَسُولِ اللَّهِ ﷺ وَهُوَ بِالْبَطْحَاءِ فَقَالَ أَحَجَجْتَ قُلْتُ نَعَمْ قَالَ بِمَا أَهْلَلْتَ قُلْتُ لَبَّيْكَ بِإِهْلاَلٍ كَإِهْلاَلِ النَّبِيِّ ﷺ قَالَ أَحْسَنْتَ انْطَلِقْ فَطُفْ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ ثُمَّ أَتَيْتُ امْرَأَةً مِنْ نِسَاءِ بَنِي قَيْسٍ فَفَلَتْ رَأْسِي ثُمَّ أَهْلَلْتُ بِالْحَجِّ فَكُنْتُ أُفْتِي بِهِ النَّاسَ حَتَّى خِلاَفَةِ عُمَرَ ؓ فَذَكَرْتُهُ لَهُ فَقَالَ إِنْ نَأْخُذْ بِكِتَابِ اللَّهِ فَإِنَّهُ يَأْمُرُنَا بِالتَّمَامِ وَإِنْ نَأْخُذْ بِسُنَّةِ رَسُولِ اللَّهِ ﷺ فَإِنَّ رَسُولَ اللَّهِ ﷺ لَمْ يَحِلَّ حَتَّى بَلَغَ الْهَدْىُ مَحِلَّهُ
