حَدَّثَنَا عَبِيدَةُ بْنُ حُمَيْدٍ عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ عَنْ مُجَاهِدٍ عَنِ ابْنِ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لِأَصْحَابِهِ اجْعَلُوهَا عُمْرَةً فَإِنِّي لَوْ اسْتَقْبَلْتُ مِنْ أَمْرِي مَا اسْتَدْبَرْتُ لَأَمَرْتُكُمْ بِهَا وَيَحِلُّ مَنْ لَيْسَ مَعَهُ هَدْيٌ وَكَانَ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ هَدْيٌ قَالَ وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَخَلَتْ الْعُمْرَةُ فِي الْحَجِّ إِلَى يَوْمِ الْقِيَامَةِ وَخَلَّلَ بَيْنَ أَصَابِعِهِ
مسند امام احمد بن حنبل · Hadith 2348
It was narrated from Ibn 'Abbas (RA) that the Messenger of Allah (PBUH) said to his companions: "Make it 'Umrah. If I had known before what I know now, I would have told you to do it ('Umrah). And let those who do not have sacrificial animals with them exit ihram." The Messenger of Allah (PBUH) had a sacrificial animal with him. And the Messenger of Allah (PBUH) said: "'Umrah has been incorporated into Hajj until the Day of Resurrection." And he interlaced his fingers.
