Sahih Muslim 1250aBook 15, Hadith 234
حَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا ابْنُ مَهْدِيٍّ، حَدَّثَنِي سَلِيمُ بْنُ حَيَّانَ، عَنْ مَرْوَانَ الأَصْفَرِ، عَنْ أَنَسٍ، - رضى الله عنه - أَنَّ عَلِيًّا، قَدِمَ مِنَ الْيَمَنِ فَقَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم " بِمَ أَهْلَلْتَ " . فَقَالَ أَهْلَلْتُ بِإِهْلاَلِ النَّبِيِّ صلى الله عليه وسلم . قَالَ " لَوْلاَ أَنَّ مَعِيَ الْهَدْىَ لأَحْلَلْتُ " .
With (what intention) have you put on Ihram? He said: I have put on Ibram in accordance with the intention with which Allah's Apostle (ﷺ) has put on Ibram, whereupon he (the Holy Prophet) said: Had there not been the sacrificial animals with me, I would have put off Ihram (after performing 'Umra).
