Narrated Al-Bara':
حَدَّثَنَا حَجَّاجٌ ، قَالَ حَدَّثَنَا شُعْبَةُ ، قَالَ أَخْبَرَنِي زُبَيْدٌ ، قَالَ سَمِعْتُ الشَّعْبِيَّ ، عَنِ الْبَرَاءِ ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَخْطُبُ فَقَالَ " إِنَّ أَوَّلَ مَا نَبْدَأُ مِنْ يَوْمِنَا هَذَا أَنْ نُصَلِّيَ، ثُمَّ نَرْجِعَ فَنَنْحَرَ، فَمَنْ فَعَلَ فَقَدْ أَصَابَ سُنَّتَنَا " .
I heard the Prophet (p.b.u.h) delivering a Khutba saying, "The first thing to be done on this day (first day of `Id ul Adha) is to pray; and after returning from the prayer we slaughter our sacrifices (in the name of Allah) and whoever does so, he acted according to our Sunna (traditions)."
