A man found that the day of 'Id al-Adha coincided with the day of his son's 'aqiqah; is it permissible for him to slaughter one animal for both the 'Id sacrifice and the 'aqiqah?

The questioner : A man said, "If the day of 'Id al-Adha, when the slaughter takes place, coincides with the day of my son's 'aqiqah, is one animal sufficient for both?" I told him, "The Shaykh says it is not sufficient, because this is obligatory and this is obligatory, so one does not drop the other." He said, "Which one? I mean, I can only afford to slaughter one. Which one do I prioritize, this one or that one?" I told him, "You can prioritize the 'Id sacrifice, because the 'aqiqah has the seventh, fourteenth, and twenty-first days, so you have room. May Allah make it easy for you, so you perform the 'Id sacrifice first, as its time is limited to the four days."

The Shaykh : The questioner is asking when it is possible; he is asking about the time of the 'Id sacrifice and the time of the 'aqiqah.

The questioner : Ah, the end of the period. I mean, we understood from the Shaykh that if he says the seventh day of the 'Id sacrifice, the seventh means the first, meaning the first day of the 'Id sacrifice will be the first day of the seventh.

The Shaykh : I am not concerned with that; I am concerned with the answer to any question of this nature.

The questioner : Yes, may Allah reward you with good.
