[Machine] A man asked the Prophet ﷺ and said, "O Messenger of Allah, I slaughtered before throwing (stones during Hajj). He said, 'Throw and there is no harm.' Another man said, 'I shaved before slaughtering.' He said, 'Slaughter and there is no harm.' Abu Bakr then said, 'I heard Sufyan being asked about this hadith, and Buhlul said to him, 'This is what you have memorized from Az-Zuhri, O Abu Muhammad?' He said, 'Yes, it is as if you hear it, except that he used to narrate it in a longer form. So this is what I have memorized from him.' Buhlul then said to Sufyan, 'Indeed, Abdur-Rahman ibn Mahdi said that you told him you did not memorize it.' Sufyan said, 'Abdur-Rahman ibn Mahdi speaks the truth. I did not memorize it in its entirety. As for this, I have mastered it."  

أَنَّ رَجُلًا سَأَلَ النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللهِ ذَبَحْتُ قَبْلَ أَنْ أَرْمِيَ قَالَ ارْمِ وَلَا حَرَجَ قَالَ آخَرُ حَلَقْتُ قَبْلَ أَنْ أَذْبَحَ قَالَ اذْبَحْ وَلَا حَرَجَ قَالَ أَبُو بَكْرٍ ثُمَّ سَمِعْتُ سُفْيَانَ يُسْأَلُ عَنْ هَذَا الْحَدِيثِ فَقَالَ لَهُ بُلْبُلٌ هَذَا مِمَّا حَفِظْتَ مِنَ الزُّهْرِيِّ يَا أَبَا مُحَمَّدٍ؟ قَالَ نَعَمْ كَأَنَّكَ تَسْمَعْهُ إِلَّا أَنَّهُ كَانَ يُطِيلُهُ فَهَذَا الَّذِي حَفِظْتُ مِنْهُ قَالَ وَسَمِعْتُ بُلْبُلًا قَالَ لِسُفْيَانَ إِنَّ عَبْدَ الرَّحْمَنِ بْنَ مَهْدِيٍّ قَالَ إِنَّكَ قُلْتَ لَهُ لَمْ أَحْفَظْهُ فَقَالَ سُفْيَانُ صَدَقَ ابْنُ مَهْدِيٍّ لَمْ أَحْفَظْهُ بِطُولِهِ فَأَمَّا هَذَا فَقَدْ أَتْقَنْتُهُ
