slaughter anything but a mature animal, unless that is difficult for you, in which case slaughter a yearling sheep.” (1) Since a thaniyyah is older than a jadha'ah, it would not suffice, in adherence to the apparent wording of the hadith.
In the Festival of Sacrifice sermon, he explains to them the time for offering the sacrifice: from after the Festival prayer until the end of four days—namely, the day of the Festival and the three days following it, which are the Days of Tashriq, according to the stronger view.
What the author has mentioned—that the sacrifice and the rulings connected to it should be explained in the Festival of Sacrifice sermon—is appropriate, as established by the sunnah.
The additional takbirs, the remembrance between them, and the two sermons are sunnah. Voluntary prayer before or after it at its place is disliked . . .
His statement, “The additional takbirs,” means those additional to the obligatory takbirs in the prayer. According to the view followed by the author, there are six in the first rak'ah and five in the second. He calls them additional because, in the first rak'ah, they are additional to what is a pillar, while in the second they are additional to what is obligatory.
The evidence that these additional takbirs are sunnah is that the Prophet ﷺ, in the hadith of the man who prayed incorrectly, mentioned none of the takbirs except the opening takbir. (2)
His statement, “and the remembrance between them,” means that whether it is the wording mentioned by the author—“Allahu akbar kabiran (Allah is supremely great), wa-l-hamdu lillahi kathiran (and abundant praise belongs to Allah) . . .,” etc.—or any other remembrance that a person says on his own, it is sunnah. The discussion of whether it is sunnah or not has already preceded.
His statement, “and the two sermons are sunnah,” means that the two Festival sermons are sunnah.
