The Prophet (ﷺ) 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 (ﷺ) 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 (ﷺ) said, "Whoever slaughtered (the sacrifice) after the prayer, he slaughtered it at the right time and followed the tradition of the Muslims."

The Prophet (ﷺ) said, "Whoever slaughtered the sacrifice before the prayer, he just slaughtered it for himself, and whoever slaughtered it after the prayer, he slaughtered it at the right time and followed the tradition of the Muslims."

that the Prophet (ﷺ) distributed among his companions some animals for sacrifice (to be slaughtered on `Id-al-Adha). `Uqba's share was a Jadha'a (a six month old goat). `Uqba said, "O Allah's Messenger (ﷺ)! I get in my share of Jadha'a (a six month old ram)." The Prophet (ﷺ) said, "Slaughter it as a sacrifice."

that the Prophet (ﷺ) entered upon her when she had her menses at Sarif before entering Mecca, and she was weeping (because she was afraid that she would not be able to perform the Hajj). The Prophet (ﷺ) said, "What is wrong with you? Have you got your period?" She said, "Yes." He said, "This is a matter Allah has decreed for all the daughters of Adam, so perform all the ceremonies of Hajj like the others, but do not perform the Tawaf around the Ka`ba." `Aisha added: When we were at Mina, beef was brought to me and I asked, "What is this?" They (the people) said, "Allah's Messenger (ﷺ) has slaughtered some cows as sacrifices on behalf of his wives."

The Prophet (ﷺ) said on the day of Nahr, "Whoever has slaughtered his sacrifice before the prayer, should repeat it (slaughter another sacrifice)." A man got up and said, "O Allah's Messenger (ﷺ)! This is a day on which meat is desired." He then mentioned his neighbors saying, "I have a six month old ram which is to me better than the meat of two sheep." The Prophet (ﷺ) allowed him to slaughter it as a sacrifice, but I do not know whether this permission was valid for other than that man or not. The Prophet (ﷺ) then went towards two rams and slaughtered them, and then the people went towards some sheep and distributed them among themselves.
