Sahih Bukhari 1559

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ ، حَدَّثَنَا سُفْيَانُ ، عَنْ قَيْسِ بْنِ مُسْلِمٍ ، عَنْ طَارِقِ بْنِ شِهَابٍ ، عَنْ أَبِي مُوسَى رَضِيَ اللَّهُ عَنْهُ ، قَالَ : بَعَثَنِي النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِلَى قَوْمٍ بِالْيَمَنِ ، فَجِئْتُ وَهُوَ بِالْبَطْحَاءِ ، فَقَالَ : بِمَا أَهْلَلْتَ ؟ , قُلْتُ : أَهْلَلْتُ كَإِهْلَالِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ , قَالَ : هَلْ مَعَكَ مِنْ هَدْيٍ ؟ , قُلْتُ : لَا ، فَأَمَرَنِي ، فَطُفْتُ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ ، ثُمَّ أَمَرَنِي فَأَحْلَلْتُ فَأَتَيْتُ امْرَأَةً مِنْ قَوْمِي فَمَشَطَتْنِي أَوْ غَسَلَتْ رَأْسِي ، فَقَدِمَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ ، فَقَالَ : إِنْ نَأْخُذْ بِكِتَابِ اللَّهِ فَإِنَّهُ يَأْمُرُنَا بِالتَّمَامِ ، قَالَ اللَّهُ : وَأَتِمُّوا الْحَجَّ وَالْعُمْرَةَ لِلَّهِ سورة البقرة آية 196 ، وَإِنْ نَأْخُذْ بِسُنَّةِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَإِنَّهُ لَمْ يَحِلَّ حَتَّى نَحَرَ الْهَدْيَ .

Narrated Abu Musa: The Prophet sent me to some people in Yemen and when I returned, I found him at Al-Batha. He asked me, With what intention have you assumed Ihram (i.e. for Hajj or for Umra or for both? ) I replied, I have assumed Ihram with an intention like that of the Prophet. He asked, Have you a Hadi with you? I replied in the negative. He ordered me to perform Tawaf round the Ka`ba and between Safa and Marwa and then to finish my Ihram. I did so and went to a woman from my tribe who combed my hair or washed my head. Then, when `Umar came (i.e. became Caliph) he said, If we follow Allah's Book, it orders us to complete Hajj and Umra; as Allah says: Perform the Hajj and Umra for Allah. (2.196). And if we follow the tradition of the Prophet who did not finish his Ihram till he sacrificed his Hadi.
