What is the validity of the argument of those who cited the hadith (so let them pour out blood for it) to prove that the 'aqiqah is not restricted to a sheep?

The questioner : Ma'lish, , how authentic is this hadith .

The Shaykh : It is an authentic hadith regarding the 'aqiqah.

The questioner : The argument for it is that any blood can be slaughtered.

The Shaykh : No, this blood is explained by other hadiths as a sheep; the specific explanation takes precedence over the general.

The questioner : Is it permissible to slaughter one sheep after another? That is, to slaughter a sheep for his child, and then another one later, intending to slaughter two sheep, and the father is able to slaughter one now and, if Allah wills, slaughter the other after a period of time? Is that permissible?

The Shaykh : I wonder if it is permissible if he is not able to slaughter even one now.

The questioner: Yes.

The Shaykh : Is it permissible if he slaughters it later?

The questioner: Yes.

The Shaykh : The Shaykh: The answer: Yes.

The questioner : May Allah reward you with all good. May Allah do you good.

The Shaykh: Amen.
