كتاب العيدين
Read the English translation first, with the original Arabic directly underneath.
Narrated Anas:
The Prophet (ﷺ) said, "Whoever slaughtered (his sacrifice) before the `Id prayer, should slaughter again." A man stood up and said, "This is the day on which one has desire for meat," and he mentioned something about his neighbors. It seemed that the Prophet (ﷺ) I believed him. Then the same man added, "I have a young she-goat which is dearer to me than the meat of two sheep." The Prophet (ﷺ) permitted him to slaughter it as a sacrifice. I do not know whether that permission was valid only for him or for others as well.
