Sunan an-Nasa'i 4396
It was narrated that Anas said:
"The Messenger of Allah said on the Day of Sacrifice:' Whoever slaughtered his sacrifice before the prayer, let him repeat it.' A man stood up and said: 'O Messenger of Allah, this is a day when people want to eat meat.' He mentioned that his neighbors were poor and it was as if the Messenger of Allah believed him. He said: 'I have a Jadh'ah that is dearer to me than tow sheep for meat.; So he granted him a concession (allowing him to sacrifice it) but I do not know whether it applied to anyone else or not. Then he went toward two rams and sacrificed them." (Sahih )
أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا ابْنُ عُلَيَّةَ، قَالَ حَدَّثَنَا أَيُّوبُ، عَنْ مُحَمَّدٍ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمَ النَّحْرِ ‏
"‏ مَنْ كَانَ ذَبَحَ قَبْلَ الصَّلاَةِ فَلْيُعِدْ ‏"‏ ‏.‏ فَقَامَ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ هَذَا يَوْمٌ يُشْتَهَى فِيهِ اللَّحْمُ فَذَكَرَ هَنَةً مِنْ جِيرَانِهِ كَأَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَدَّقَهُ ‏.‏ قَالَ عِنْدِي جَذَعَةٌ هِيَ أَحَبُّ إِلَىَّ مِنْ شَاتَىْ لَحْمٍ ‏.‏ فَرَخَّصَ لَهُ فَلاَ أَدْرِي أَبَلَغَتْ رُخْصَتُهُ مَنْ سِوَاهُ أَمْ لاَ ثُمَّ انْكَفَأَ إِلَى كَبْشَيْنِ فَذَبَحَهُمَا ‏.‏
