Mishkat al-Masabih 4 Prayer كتاب الصلاة 839

وَعَنِ ابْنِ عُمَرَ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَذْبَحُ وَيَنْحَرُ بِالْمُصَلَّى. رَوَاهُ البُخَارِيّ

Ibn ‘Umar said that God’s Messenger used to sacrifice and slaughter at the place of prayer. Bukhari transmitted it. Idain , 22, where “the Prophet” occurs in place of “God’s Messenger.”
