Reading from the author's text with commentary and collation of manuscripts: "The third

The reader: "The third: If slaughtering at the location of the festival had been permissible, the Prophet (peace and blessings be upon him) would have allowed the one who made a vow to fulfill it, just as he allowed the woman who vowed to strike the hand drum to do so; rather, he would have made fulfilling it obligatory, since slaughtering at the vowed location is obligatory. And if slaughtering at the location of their festival is prohibited, how is it with agreeing with them in the festival itself by performing some of the actions done on account of their festival? This is clarified by the fact that 'festival' is a name"

The Shaykh : And it has reached us that some foolish people weak in religion exchange gifts on the festivals of the Christians. And this is forbidden and not permissible, because in that there is pleasing them and approval of what they are upon of disbelief and of their religion by which they profess faith. We complain to Allah. Yes.
The reader: "This is clarified by the fact that 'festival' is a name for what recurs of general gathering in a customary manner, recurring either by the recurrence of the year, or the week, or the month, or the like. So the festival gathers matters: among them is a recurring day, like the day of 'Id al-Fitr and the day of Jumu'ah. Among them is a gathering in it. Among them are actions that follow that: from acts of worship and customs. And the festival may be specific to a particular place, or it may be general. And all of these matters may be called a festival. So the time, as the saying of the Prophet (peace and blessings be upon him) regarding the day of Jumu'ah:

Allah has made this day a festival day (id)

إن هذا يوم جعله الله للمسلمين عيدا

Muwatta Malik 2:113

And the gathering and actions, as the saying of Ibn 'Abbas:

Have you been present along with the Messenger of Allah (ﷺ)

شهدت العيد مع رسول الله صلى الله عليه وسلم

Sunan Abi Dawud 1146Sahih (Al-Albani)

And the place, as the saying of the Prophet (peace and blessings be upon him):

Do not take my grave as a festival

لا تتخذوا قبري عيدا

Musannaf Ibn Abi Shaybah 5:1006

And the word 'festival' may be a name for the combination of the day and the action in it, which is the common usage, as the saying of the Prophet (peace and blessings be upon him):

Leave them, O Abu Bakr, for every people have a festival, and this is our festival

دعهما يا أبا بكر فإن لكل قوم عيدا وإن هذا عيدنا

So the saying of the Prophet (peace and blessings be upon him):

Is there a festival of their festivals in it?

هل بها عيد من أعيادهم

means a customary gathering from their gatherings that were a festival. So when he said: No, he said to him: "Fulfill your vow." And this implies that the fact that the area is a place for their festival is a barrier to slaughtering in it—even if one has vowed—just as the fact that it is the location of their idols is a barrier. Otherwise, the speech would not be coherent, and the specification would not be appropriate. And it is known that this is only for the exaltation of the area which they exalt by celebrating in it, or for participating with them in celebrating in it, or for reviving the symbol of their festival in it, or the like; for it is nothing but the place of the action, or the action itself, or its time. If it is for the specification of the area—and this is the apparent meaning—then he prohibited the specification of the area because it is the location of their festival. And for this reason, when it was devoid of that, he permitted slaughtering in it, and the intention of specification remained. So it is known: that the thing to be avoided is the specification of the area of their festival. And if the specification of the area of their festival is to be avoided, how is it with their festival itself? And this"

The Shaykh : Eid.
The student: As he read

The Shaykh : Itself? Here, what is it?
The student: Mahdhur (thing to be avoided)

The Shaykh : Mahdhur (thing to be avoided)
The student: With a dhal or a dhad?

The Shaykh : With a dhal, in my opinion.
The student: In your opinion, with a dhal?

The Shaykh : Yes, indeed.
The student: Why?

The Shaykh : Mahdhur (thing to be avoided), because the Messenger (peace and blessings be upon him) warned against this, that one should not specify, specifying the area of the festival.
The reader: "This is just as it"

The Shaykh : And this
The reader: I will add it, O Shaykh.

The Shaykh : And this, yes.
The reader: Addition.

The Shaykh : How is it with their festival itself, and this
The student: O Shaykh

The Shaykh : The time for questions has come. Yes.
