"I came from Yemen and the Prophet had stopped in Al-Batha at the time to Hajj. He asked: 'Have you performed Hajj?' I said: 'Yes, He said: 'What did you say?' I said; 'Labbaika bi ihlal ka ihlal in-nabiy (Here I am (O Allah, entering Ihram for that for which the Prophet entered Ihram). He said 'Circumambulate the House and (perform Sa) between As-Safa and Al-Marwah, and exit Ihram.' Then I went to a woman who combed my hair. I started to issue Fatwas to the people based on that. Then during the Khilafah of 'Umar, a man said to me: 'O abu Musa, withhold some of our Fatwas from us, for you do not know what the Commander of the Believers has introduced into the rites after you.''' Abu Musa said: "O people, O people, whoever heard our Fatwa,let him not rush to follow it, for the Commander of the Believers is coming to your and you should follow him.: 'Umar said: "If we follow the Book of Allah, then indeed He commands us to complete Hajj and 'Umrah, and the Messenger of Allah did not exit Ihram until the Hadi had reached its place." (Using translation from Nasāʾī 2742)
قَالَ أَبُو مُوسَى أَقْبَلْتُ مِنَ الْيَمَنِ وَالنَّبِيُّ ﷺ مُنِيخٌ بِالْبَطْحَاءِ حَيْثُ حَجَّ فَقَالَ «حَجَجْتَ؟» قُلْتُ نَعَمْ قَالَ «كَيْف»؟ قُلْتُ قَالَ قُلْتُ لَبَّيْكَ بِإِهْلَالٍ كَإِهْلَالِ النَّبِيِّ ﷺ قَالَ «فَطُفْ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ» وَأَحَلَّ فَفَعَلْتُ ثُمَّ أَتَيْتُ امْرَأَةً فَفَلَّتْ رَأْسِي فَجَعَلْتُ أُفْتِي النَّاسَ بِذَلِكَ قَالَ قُلْتُ إِنَّ أَمِيرَ الْمُؤْمِنِينَ قَادِمٌ عَلَيْكُمْ فَائْتَمُّوا بِهِ فَقَالَ عُمَرُ إنْ نَأْخُذْ بِكِتَابِ اللهِ فَإِنَّهُ يَأْمُرُنَا بِالتَّمَامِ وَإِنْ نَأْخُذْ بِسُنَّةِ النَّبِيِّ ﷺ فَإِنَّ النَّبِيَّ ﷺ لَمْ يَحِلَّ حَتَّى بَلَغَ الْهَدْيُ مَحِلَّهُ
