[Machine] The Prophet ﷺ said, "Whoever sacrifices before the prayer, then he has only slaughtered for himself. And whoever sacrifices after the prayer, then his sacrifice is complete and he has followed the tradition of the Muslims." Abu Abdullah al-Hafiz informed us, Abu Abdullah Muhammad ibn Ya'qub narrated to me, who narrated from Muhammad ibn Abdus-Salam, who narrated from Yahya ibn Yahya, who narrated from Khalid ibn Abdullah, from Mutarraf, who mentioned it.
قَالَ النَّبِيُّ ﷺ مَنْ ضَحَّى قَبْلَ الصَّلَاةِ فَإِنَّمَا ذَبَحَ لِنَفْسِهِ وَمَنْ ذَبَحَ بَعْدَ الصَّلَاةِ فَقَدْ تَمَّ نُسُكُهُ وَأَصَابَ سُنَّةَ الْمُسْلِمِينَ أَخْبَرَنَاهُ أَبُو عَبْدِ اللهِ الْحَافِظُ أنبأ أَبُو عَبْدِ اللهِ مُحَمَّدُ بْنُ يَعْقُوبَ حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ السَّلَامِ ثنا يَحْيَى بْنُ يَحْيَى أنبأ خَالِدُ بْنُ عَبْدِ اللهِ عَنْ مُطَرِّفٍ فَذَكَرَهُ
