صحيح البخاري#1999Sahihحَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ الصِّيَامُ لِمَنْ تَمَتَّعَ بِالْعُمْرَةِ إِلَى الْحَجِّ، إِلَى يَوْمِ عَرَفَةَ، فَإِنْ لَمْ يَجِدْ هَدْيًا وَلَمْ يَصُمْ صَامَ أَيَّامَ مِنًى. وَعَنِ ابْنِ شِهَابٍ عَنْ عُرْوَةَ عَنْ عَائِشَةَ مِثْلَهُ. تَابَعَهُ إِبْرَاهِيمُ بْنُ سَعْدٍ عَنِ ابْنِ شِهَابٍ.
Narrated Ibn `Umar:Fasting for those who perform ,Hajj-at-Tamattu` (in lieu of the Hadi which they cannot afford) may be performed up to the day of `Arafat. And if one does not get a Hadi and has not fasted (before the `Id) then one should fast of the days of Mina. (11th, 12th and 13th of Dhul Hijjah)
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
