Abu Dawud

Benefits and Issues:
This hadith is also authentic in its chain of narration.
Whereas in Sunan al-Nasa’i (Hadith 4224), the mention of two rams is found.
Shaykh al-Albani has declared it to be more authentic (asahh).
Furthermore, in Irwa’ al-Ghalil (4/379-384), after discussing all the chains of this narration, he has finally expressed the opinion
that both types of narrations exist:
those mentioning one ram, and those mentioning two rams.
However, the narrations mentioning two rams are more preponderant and more worthy of being acted upon for two reasons:
Firstly, there is an addition in them, and the addition of a trustworthy narrator is accepted.
Secondly, in the verbal narrations, the mention is of two animals,
so these other narrations become in agreement with the verbal narration.
Imam Ibn al-Qayyim rahimahullah has written
that the principles of the Shari’ah also require that two animals be slaughtered for a boy,
because the Shari’ah has granted superiority to the male over the female in several rulings.
(Tuhfat al-Mawdud, p. 79, published by Dar al-Kitab al-‘Arabi)

In the narrations, mention is made of a goat, sheep, and ram; therefore, these are the animals that should be slaughtered for ‘aqiqah. Slaughtering a cow or camel for ‘aqiqah is not established by any authentic hadith. Furthermore, there is no reason to draw an analogy between ‘aqiqah and sacrifice (udhiyah), because sacrifice is performed by everyone on specified days, whereas ‘aqiqah is performed by each household on the seventh day after the birth of their child. The very institution of ‘aqiqah is different from that of sacrifice. In the case of a boy’s ‘aqiqah, it is explicitly mentioned that two goats are to be slaughtered; therefore, for ‘aqiqah, a goat, she-goat, sheep, or ram, etc., should be slaughtered, and a cow or camel should not be slaughtered.

«أخرجه أبوداود، الأضاحي، باب في العقيقة، حديث:2841، وهو في علل الحديث لا بن أبي حاتم:2 /49، حديث:1631، وحديث أنس: أخرجه ابن حبان (الموارد)، حديث:1061 وهو حديث صحيح.»©Explanation:
Clarification: A brief mention of Hasan (radi Allahu anhu) has already been given under the chapter of the Description of Prayer (Bab Sifat al-Salat) in the Book of Prayer (Kitab al-Salat), and Husayn (radi Allahu anhu) was the brother of Hasan (radi Allahu anhu) and approximately one year younger than him.
Both were the grandsons of the Messenger of Allah (sallallahu alayhi wa sallam) and his fragrance.
In the year 61 AH, on the day of Ashura, he was martyred in the land of Iraq, in the field of Karbala.
At that time, his age was 54 years.
