Eid Mubarak !

Hadiths on `Eid Al-Adha from Sahih Al-Bukhari


Volume 7, Book 68, Number 453:

Narrated Al-Bara:

The Prophet said (on the day of Idal-Adha), "The first thing we will
do on this day of ours, is to offer the ('Id) prayer and then return
to slaughter the sacrifice. Whoever does so, he acted according to
our Sunna (tradition), and whoever slaughtered (the sacrifice) before
the prayer, what he offered was just meat he presented to his family,
and that will not be considered as Nusak (sacrifice)." (On hearing
that) Abu Burda bin Niyar got up, for he had slaughtered the
sacrifice before the prayer, and said, "I have got a six month old
ram." The Prophet said, 'Slaughter it (as a sacrifice) but it will
not be sufficient for any-one else (as a sacrifice after you). Al-
Bara' added: The Prophet said, "Whoever slaughtered (the sacrifice)
after the prayer, he slaughtered it at the right time and followed
the tradition of the Muslims."
