Narrated 'Abdullah: The Prophet said, "Abusing a Muslim is Fusuq (an evil doing) and killing him is Kufr (disbelief)."

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)."

Narrated Al-Bara' bin `Azib: The Prophet (p.b.u.h) said, "The first thing that we should do on this day of ours is to pray and then return to slaughter the sacrifice. So anyone who does so, he acted according to our Sunna (tradition), and whoever slaughtered the sacrifice before the prayer, it was just meat which he presented to his family and would not be considered as Nusuk." A person from the Ansar named Abu Burda bin Niyyar said, "O Allah's Apostle! I slaughtered the Nusuk (before the prayer) but I have a young shegoat which is better than an older sheep." The Prophet I said, "Sacrifice it in lieu of the first, but it will be not sufficient (as a sacrifice) for anybody else after you."

Narrated Al-Bara': The Prophet delivered the Khutba on the day of Nahr (`Id-ul-Adha) and said, "The first thing we should do on this day of ours is to pray and then return and slaughter (our sacrifices). So anyone who does so he acted according to our Sunna; and whoever slaughtered before the prayer then it was just meat that he offered to his family and would not be considered as a sacrifice in any way. My uncle Abu Burda bin Niyyar got up and said, "O, Allah's Apostle! I slaughtered the sacrifice before the prayer but I have a young she-goat which is better than an older sheep." The Prophet said, "Slaughter it in lieu of the first and such a goat will not be considered as a sacrifice for anybody else after you."

Narrated Al-Bara': The Prophet went towards Al-Baqi (the graveyard at Medina) on the day of Id-ul-Adha and offered a two-rak`at prayer (of `Id-ul-Adha) and then faced us and said, "On this day of ours, our first act of worship is the offering of prayer and then we will return and slaughter the sacrifice, and whoever does this concords with our Sunna; and whoever slaughtered his sacrifice before that (i.e. before the prayer) then that was a thing which he prepared earlier for his family and it would not be considered as a Nusuk (sacrifice.)" A man stood up and said, "O, Allah's Apostle! I slaughtered (the animal before the prayer) but I have a young she-goat which is better than an older sheep." The Prophet (p.b.u.h) said to him, "Slaughter it. But a similar sacrifice will not be sufficient for anybody else after you."

Narrated `Abdullah: the Prophet said, "He who slaps his cheeks, tears his clothes and follows the ways and traditions of the Days of Ignorance is not one of us."

Narrated `Abdullah (bin Mas`ud): The Prophet said, "Who-ever slaps his face or tears the bosom of his dress, or calls the calls of the Period of Ignorance, is not from us."

Narrated Ibn `Umar: The Prophet said, "There is a tree among the trees which is similar to a Muslim (in goodness), and that is the date palm tree."

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."

Narrated Al-Bara' bin `Azib: An uncle of mine called Abu Burda, slaughtered his sacrifice before the `Id prayer. So Allah's Apostle said to him, "Your (slaughtered) sheep was just mutton (not a sacrifice)." Abu Burda said, "O Allah's Apostle! I have got a domestic kid." The Prophet said, "Slaughter it (as a sacrifice) but it will not be permissible for anybody other than you" The Prophet added, "Whoever slaughtered his sacrifice before the (`Id) prayer, he only slaughtered for himself, and whoever slaughtered it after the prayer, he offered his sacrifice properly and followed the tradition of the Muslims."

Narrated Al-Bara': I heard the Prophet delivering a sermon, and he said (on the Day of `Id-Allah. a), "The first thing we will do on this day of ours is that we will offer the `Id prayer, then we will return and slaughter our sacrifices; and whoever does so, then indeed he has followed our tradition, and whoever slaughtered his sacrifice (before the prayer), what he offered was just meat that he presented to his family, and that was not a sacrifice." Abu Burda got up and said, "O Allah's Apostle! I slaughtered the sacrifice before the prayer and I have got a Jadha'a which is better than an old sheep." The Prophet said, "Slaughter it to make up for that, but it will not be sufficient for anybody else after you."

Narrated `Ali: The Prophet , sent an army and appointed some man their commander The man made a fire and then said (to the soldiers), "Enter it." Some of them intended to enter it while some others said, 'We have run away from it (i.e., embraced Islam to save ourselves from the 'fire')." They mentioned that to the Prophet, and he said about people who had intended to enter the fire. ''If they had entered it, they would have remained In it till the Day of Resurrection.'' Then he said to others, "No obedience for evil deeds, obedience is required only in what is good ."
