What is the ruling on one who intends to make the hady or the udhiyah a charity?

The questioner : Well, if you make it a charity, is it different from the udhiyah?

The Shaykh : I mean, do you want to combine charity with the udhiyah? Or do you want to make the udhiyah a charity?

The questioner : The intention is that it not be an udhiyah, but rather a charity.

The Shaykh : If you want to make it a charity, then it is a charity among charities, meaning exactly like zakat al-fitr. He (peace and blessings be upon him) said: So I tell you now: if you make the udhiyah a charity, you have not performed the udhiyah, and there is no difference at that point between giving charity with a slaughtered animal before the festival, or after the festival, or on any day of the year; it is a charity among charities. But, without holding you to blame, the analogy at that point would be like "building a palace and demolishing a fortress." Why? Because you neglected the obligatory and came with the recommended. And the Messenger (peace and blessings be upon him) says:
The Shaykh : And it was agreed upon in his (peace and blessings be upon him) time that some of them sacrificed on the day of the festival before the festival prayer, so he said to him: Because it is a condition that it be after the festival prayer, as you know. So, since the Messenger (peace and blessings be upon him) ordered him to make up for it, this confirms its obligation. Therefore, the one who truly wants to give charity should not forget himself, nor forget performing the obligatory. So he performs the udhiyah, and then, as we said earlier, he eats a few bites from it, and stores a few bites, and then gives the majority of it as charity.
