Volume 2, Book 15, Number 71:
Narrated Al-Bara’:
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).”
