Sahih al-Bukhari · Book 25: Hajj (Pilgrimage) · “...And whosoever performs the ‘Umra in the months of Hajj before (performing) the Hajj (i.e. Hajj-al-Qiran and Hajj-at-Tamattu‘) he must slaughter an animal (Hady) such as he can afford it... till... present at the Al-Masjid-al-Haram (at Makkah)...” (V.2:196)
Narrated Abu Jamra:
حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ ، أَخْبَرَنَا النَّضْرُ ، أَخْبَرَنَا شُعْبَةُ ، حَدَّثَنَا أَبُو جَمْرَةَ ، قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ عَنِ الْمُتْعَةِ، فَأَمَرَنِي بِهَا، وَسَأَلْتُهُ عَنِ الْهَدْىِ، فَقَالَ فِيهَا جَزُورٌ أَوْ بَقَرَةٌ أَوْ شَاةٌ أَوْ شِرْكٌ فِي دَمٍ قَالَ وَكَأَنَّ نَاسًا كَرِهُوهَا، فَنِمْتُ فَرَأَيْتُ فِي الْمَنَامِ كَأَنَّ إِنْسَانًا يُنَادِي حَجٌّ مَبْرُورٌ، وَمُتْعَةٌ مُتَقَبَّلَةٌ. فَأَتَيْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ فَحَدَّثْتُهُ فَقَالَ اللَّهُ أَكْبَرُ سُنَّةُ أَبِي الْقَاسِمِ صلى الله عليه وسلم قَالَ وَقَالَ آدَمُ وَوَهْبُ بْنُ جَرِيرٍ وَغُنْدَرٌ عَنْ شُعْبَةَ عُمْرَةٌ مُتَقَبَّلَةٌ، وَحَجٌّ مَبْرُورٌ.
I asked Ibn `Abbas about Hajj-at-Tamattu`. He ordered me to perform it. I asked him about the Hadi (sacrifice). He said, "You have to slaughter a camel, a cow or a sheep, or you may share the Hadi with the others." It seemed that some people disliked it (Hajj-at-Tamattu`). I slept and dreamt as if a person was announcing: "Hajj Mabrur and accepted Mut'ah (Hajj-at-Tamattu`)" I went to Ibn `Abbas and narrated it to him. He said, "Allah is Greater. (That was) the tradition of Abu Al-Qasim (i.e. Prophet). Narrated Shu`ba that the call in the dream was. "An accepted `Umra and Hajj-Mabrur. "
