I came to the Messenger of Allah ﷺ when he was in al-Bathaʿ and he said: ʿWhat did you enter ihram for?ʿ I said: I have entered ihram for the same as the Prophet ﷺ did. He said: ʿHave you brought a sacrificial animal?ʿ I said: No. He said: “Circumambulate the House and go between as-Safa and al-Marwah, then exit ihraam.” So I circumambulated the House and went between as-Safa and al-Marwah, then I went to a woman of my people and she combed my hair and washed my head. I used to give fatwas on that basis during the caliphate of Abu Bakr and ‘Umar. During one season when I was performing Hajj, a man came to me and said: You do not know the latest fatwa of Ameer al-Muʿmineen concerning the Hajj. I said: O people, if we gave a fatwa, Ameer al-Muʿmineen is coming to you, so follow him in performing Hajj. When he came I said: What is this thing that you have introduced to the rituals [of Hajj]? He said: We see in the Book of Allah that Allah, may He be exalted, says: ʿAnd perform properly (i.e. all the ceremonies according to the ways of Prophet Muhammad ﷺ, the Hajj and ‘Umrah (i.e. the pilgrimage to Makkah) for Allahʿ [al-Baqarah 2:196], and if we follow the Sunnah of our Prophet ﷺ, he did not exit ihraam until he offered the sacrifice.

لِي النَّبِيُّ ﷺ بِمَ أَهْلَلْتَ؟ قَالَ قُلْتُ بِإِهْلَالٍ كَإِهْلَالِ النَّبِيِّ ﷺ قَالَ فَقَالَ هَلْ مَعَكَ مِنْ هَدْيٍ؟ قَالَ قُلْتُ يَعْنِي لَا قَالَ فَأَمَرَنِي فَطُفْتُ بِالْبَيْتِ وَبَيْنَ الصَّفَا وَالْمَرْوَةِ ثُمَّ أَتَيْتُ امْرَأَةً مِنْ قَوْمِي فَمَشَطَتْ رَأْسِي وَغَسَلَتْهُ ثُمَّ أَحْلَلْتُ فَلَمَّا كَانَ يَوْمُ التَّرْوِيَةِ أَهْلَلْتُ بِالْحَجِّ قَالَ فَكُنْتُ أُفْتِي النَّاسَ بِذَلِكَ إِمَارَةَ أَبِي بَكْرٍ وَعُمَرَ فَبَيْنَا أَنَا وَاقِفٌ فِي سُوقِ الْمَوْسِمِ إِذْ جَاءَ رَجُلٌ فَسَارَّنِي فَقَالَ إِنَّكَ لَا تَدْرِي مَا أَحْدَثَ أَمِيرُ الْمُؤْمِنِينَ فِي شَأْنِ النُّسُكِ قَالَ قُلْتُ أَيُّهَا النَّاسُ مَنْ كُنَّا أَفْتَيْنَاهُ فِي شَيْءٍ فَلْيَتَّئِدْ فَهَذَا أَمِيرُ الْمُؤْمِنِينَ قَادِمٌ عَلَيْكُمْ فَبِهِ فَأْتَمُّوا قَالَ فَقَالَ لِي إِنْ نَأْخُذْ بِكِتَابِ اللهِ تَعَالَى فَإِنَّهُ يَأْمُرُ بِالتَّمَامِ وَإِنْ نَأْخُذْ بِسُنَّةِ نَبِيِّنَا ﷺ فَإِنَّهُ لَمْ يَحِلَّ حَتَّى نَحَرَ الْهَدْيَ
