Sahih al-Bukhari 7229Book 94, Hadith 4
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، حَدَّثَنِي عُرْوَةُ، أَنَّ عَائِشَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لَوِ اسْتَقْبَلْتُ مِنْ أَمْرِي مَا اسْتَدْبَرْتُ مَا سُقْتُ الْهَدْىَ، وَلَحَلَلْتُ مَعَ النَّاسِ حِينَ حَلُّوا ".
Allah's Messenger (ﷺ) said, "If I had formerly known what I came to know recently, I would not have driven the Hadi with me and would have finished the state of Ihram along with the people when they finished it."
