Sahih al-Bukhari 1572
Ibn 'Abbas said that he has been asked regarding Hajj-at-Tamattu' on which he said:
"The Muhajirin and the Ansar and the wives of the Prophet (ﷺ) and we did the same. When we reached Makkah, Allah's Messenger (ﷺ) said, "Give up your intention of doing the Hajj (at this moment) and perform 'Umra, except the one who had garlanded the Hady." So, we performed Tawaf round the Ka'bah and [Sa'y] between As-safa and Al-MArwa, slept with our wives and wore ordinary (stitched) clothes. The Prophet (ﷺ) added, "Whoever has garlanded his Hady is not allowed to finish the Ihram till the Hady has reached its destination (has been sacrificed)". Then on the night of Tarwiya (8th Dhul Hijjah, in the afternoon) he ordered us to assume Ihram for Hajj and when we have performed all the ceremonies of Hajj, we came and performed Tawaf round the Ka'bah and (Sa'y) between As-Safa and Al-Marwa, and then our Hajj was complete, and we had to sacrifice a Hady according to the statement of Allah: "... He must slaughter a Hady such as he can afford, but if he cannot afford it, he should observer Saum (fasts) three days during the Hajj and seven days after his return (to his home)…." (V. 2:196). And the sacrifice of the sheep is sufficient. So, the Prophet (ﷺ) and his Companions joined the two religious deeds, (i.e. Hajj and 'Umra) in one year, for Allah revealed (the permissibility) of such practice in His book and in the Sunna (legal ways) of His Prophet (ﷺ) and rendered it permissible for all the people except those living in Makkah. Allah says: "This is for him whose family is not present at the Al-Masjid-Al-Haram, (i.e. non resident of Makkah)." The months of Hajj which Allah mentioned in His book are: Shawwal, Dhul-Qa'da and Dhul-Hijjah. Whoever performed Hajj-at-Tamattu' in those months, then slaughtering or fasting is compulsory for him. The words: 1. Ar-Rafatha means sexual intercourse. 2. Al-Fasuq means all kinds of sin, and 3. Al-Jidal means to dispute.
وَقَالَ أَبُو كَامِلٍ فُضَيْلُ بْنُ حُسَيْنٍ الْبَصْرِيُّ حَدَّثَنَا أَبُو مَعْشَرٍ، حَدَّثَنَا عُثْمَانُ بْنُ غِيَاثٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّهُ سُئِلَ عَنْ مُتْعَةِ الْحَجِّ، فَقَالَ أَهَلَّ الْمُهَاجِرُونَ وَالأَنْصَارُ وَأَزْوَاجُ النَّبِيِّ صلى الله عليه وسلم فِي حَجَّةِ الْوَدَاعِ وَأَهْلَلْنَا، فَلَمَّا قَدِمْنَا مَكَّةَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ اجْعَلُوا إِهْلاَلَكُمْ بِالْحَجِّ عُمْرَةً إِلاَّ مَنْ قَلَّدَ الْهَدْىَ ‏"‏‏.‏ فَطُفْنَا بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ وَأَتَيْنَا النِّسَاءَ، وَلَبِسْنَا الثِّيَابَ وَقَالَ ‏"‏ مَنْ قَلَّدَ الْهَدْىَ فَإِنَّهُ لاَ يَحِلُّ لَهُ حَتَّى يَبْلُغَ الْهَدْىُ مَحِلَّهُ ‏"‏‏.‏ ثُمَّ أَمَرَنَا عَشِيَّةَ التَّرْوِيَةِ أَنْ نُهِلَّ بِالْحَجِّ، فَإِذَا فَرَغْنَا مِنَ الْمَنَاسِكِ جِئْنَا فَطُفْنَا بِالْبَيْتِ وَبِالصَّفَا وَالْمَرْوَةِ فَقَدْ تَمَّ حَجُّنَا، وَعَلَيْنَا الْهَدْىُ كَمَا قَالَ اللَّهُ تَعَالَى ‏{‏فَمَا اسْتَيْسَرَ مِنَ الْهَدْىِ فَمَنْ لَمْ يَجِدْ فَصِيَامُ ثَلاَثَةِ أَيَّامٍ فِي الْحَجِّ وَسَبْعَةٍ إِذَا رَجَعْتُمْ‏}‏ إِلَى أَمْصَارِكُمْ‏.‏ الشَّاةُ تَجْزِي، فَجَمَعُوا نُسُكَيْنِ فِي عَامٍ بَيْنَ الْحَجِّ وَالْعُمْرَةِ، فَإِنَّ اللَّهَ تَعَالَى أَنْزَلَهُ فِي كِتَابِهِ وَسَنَّهُ نَبِيُّهُ صلى الله عليه وسلم وَأَبَاحَهُ لِلنَّاسِ غَيْرَ أَهْلِ مَكَّةَ، قَالَ اللَّهُ ‏{‏ذَلِكَ لِمَنْ لَمْ يَكُنْ أَهْلُهُ حَاضِرِي الْمَسْجِدِ الْحَرَامِ‏}‏ وَأَشْهُرُ الْحَجِّ الَّتِي ذَكَرَ اللَّهُ تَعَالَى شَوَّالٌ وَذُو الْقَعْدَةِ وَذُو الْحَجَّةِ، فَمَنْ تَمَتَّعَ فِي هَذِهِ الأَشْهُرِ فَعَلَيْهِ دَمٌ أَوْ صَوْمٌ، وَالرَّفَثُ الْجِمَاعُ، وَالْفُسُوقُ الْمَعَاصِي، وَالْجِدَالُ الْمِرَاءُ‏.‏
