Full Sharh — Sahih al-Bukhari 1559
حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنْ قَيْسِ بْنِ مُسْلِمٍ، عَنْ طَارِقِ بْنِ شِهَابٍ، عَنْ أَبِي مُوسَى ـ رضى الله عنه ـ قَالَ بَعَثَنِي النَّبِيُّ صلى الله عليه وسلم إِلَى قَوْمٍ بِالْيَمَنِ فَجِئْتُ وَهْوَ بِالْبَطْحَاءِ فَقَالَ " بِمَا أَهْلَلْتَ ". قُلْتُ أَهْلَلْتُ كَإِهْلاَلِ النَّبِيِّ صلى الله عليه وسلم قَالَ " هَلْ مَعَكَ مِنْ هَدْىٍ ". قُلْتُ لاَ. فَأَمَرَنِي فَطُفْتُ بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ ثُمَّ أَمَرَنِي فَأَحْلَلْتُ فَأَتَيْتُ امْرَأَةً مِنْ قَوْمِي فَمَشَطَتْنِي، أَوْ غَسَلَتْ رَأْسِي، فَقَدِمَ عُمَرُ ـ رضى الله عنه ـ فَقَالَ إِنْ نَأْخُذْ بِكِتَابِ اللَّهِ فَإِنَّهُ يَأْمُرُنَا بِالتَّمَامِ قَالَ اللَّهُ {وَأَتِمُّوا الْحَجَّ وَالْعُمْرَةَ} وَإِنْ نَأْخُذْ بِسُنَّةِ النَّبِيِّ صلى الله عليه وسلم فَإِنَّهُ لَمْ يَحِلَّ حَتَّى نَحَرَ الْهَدْىَ.
English Translation
Narrated Abu Musa:The Prophet (ﷺ) 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 (ﷺ) who did not finish his Ihram till he sacrificed his Hadi
