وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، - يَعْنِي ابْنَ مَهْدِيٍّ - حَدَّثَنَا سُفْيَانُ، عَنْ قَيْسٍ، عَنْ طَارِقِ بْنِ شِهَابٍ، عَنْ أَبِي مُوسَى، - رضى الله عنه - قَالَ قَدِمْتُ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ مُنِيخٌ بِالْبَطْحَاءِ فَقَالَ " بِمَ أَهْلَلْتَ " . قَالَ قُلْتُ أَهْلَلْتُ بِإِهْلاَلِ النَّبِيِّ صلى الله عليه وسلم قَالَ " هَلْ سُقْتَ مِنْ هَدْىٍ " . قُلْتُ لاَ . قَالَ " فَطُفْ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ ثُمَّ حِلَّ " . فَطُفْتُ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ ثُمَّ أَتَيْتُ امْرَأَةً مِنْ قَوْمِي فَمَشَطَتْنِي وَغَسَلَتْ رَأْسِي فَكُنْتُ أُفْتِي النَّاسَ بِذَلِكَ فِي إِمَارَةِ أَبِي بَكْرٍ وَإِمَارَةِ عُمَرَ فَإِنِّي لَقَائِمٌ بِالْمَوْسِمِ إِذْ جَاءَنِي رَجُلٌ فَقَالَ إِنَّكَ لاَ تَدْرِي مَا أَحْدَثَ أَمِيرُ الْمُؤْمِنِينَ فِي شَأْنِ النُّسُكِ . فَقُلْتُ أَيُّهَا النَّاسُ مَنْ كُنَّا أَفْتَيْنَاهُ بِشَىْءٍ فَلْيَتَّئِدْ فَهَذَا أَمِيرُ الْمُؤْمِنِينَ قَادِمٌ عَلَيْكُمْ فَبِهِ فَائْتَمُّوا فَلَمَّا قَدِمَ قُلْتُ يَا أَمِيرَ الْمُؤْمِنِينَ مَا هَذَا الَّذِي أَحْدَثْتَ فِي شَأْنِ النُّسُكِ قَالَ إِنْ نَأْخُذْ بِكِتَابِ اللَّهِ فَإِنَّ اللَّهَ عَزَّ وَجَلَّ قَالَ { وَأَتِمُّوا الْحَجَّ وَالْعُمْرَةَ لِلَّهِ} وَإِنْ نَأْخُذْ بِسُنَّةِ نَبِيِّنَا عَلَيْهِ الصَّلاَةُ وَالسَّلاَمُ فَإِنَّ النَّبِيَّ صلى الله عليه وسلم لَمْ يَحِلَّ حَتَّى نَحَرَ الْهَدْىَ .
Abu Musa (Allah be pleased with him) reported:I came to the Messenger of Allah (ﷺ) and he was encamping at Batha. He (the Holy Prophet) said: With what purpose have you entered into the state of Ihram? I said: I have entered into the state of Ihram in accordance with the Ihram of Allah's Apostle (ﷺ). He said: Have you brought sacrificial animals along with you? I said: No. whereupon he said: Then circumambulate the House and run between al-Safa' and al-Marwa and put off Ihram. So I circumambulated the House, ran between al-Safa' and al-Marwa, and then came to a woman of my tribe. She combed and washed my head. I used to give religious verdict (according to the above mentioned command of the Holy Prophet) during the Caliphate of Abu Bakr and also during that of 'Umar. And it was during the Hajj season that a person came to me and said: You (perhaps) do not know what the Commander of the Believers has introduced in the rites (of Hajj). I said: 0 people, those whom we have given religious verdict about a certain thing should wait, for the Commander of the Believers is about to arrive among you, so follow him. When the Commander of the Believers arrived, I said: What is this that you have introduced in the rites (of Hajj)? -where upon he said: If we abide by the Book of Allah (we find) that there Allah, Exalted and Majestic, has said: Complete Hajj and 'Umra for Allah." And if we abide by the Sunnah of our Apostle (ﷺ) (we find) that the Messenger of Allah (May peace be upon him) did not put off Ihram till he had sacrificed the animals
