Narrated Ibn `Abbas:The Prophet (ﷺ) and his companions reached Mecca in the morning of the 4th Dhul-Hijja reciting Talbiya (O Allah! We are obedient to your orders, we respond 4 to your call) . . . intending to perform Hajj. The Prophet (ﷺ) ordered his companions to assume the lhram for Umra instead of Hajj, excepting those who had Hadi (sacrifice) with them.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنَا وُهَيْبٌ، قَالَ حَدَّثَنَا أَيُّوبُ، عَنْ أَبِي الْعَالِيَةِ الْبَرَّاءِ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ قَدِمَ النَّبِيُّ صلى الله عليه وسلم وَأَصْحَابُهُ لِصُبْحِ رَابِعَةٍ يُلَبُّونَ بِالْحَجِّ، فَأَمَرَهُمْ أَنْ يَجْعَلُوهَا عُمْرَةً إِلاَّ مَنْ مَعَهُ الْهَدْىُ. تَابَعَهُ عَطَاءٌ عَنْ جَابِرٍ.
