Tirmidhi

Explanation:
1:
Based on this weak hadith, and the supplication of the Prophet sallallahu alayhi wa sallam at the time of sacrifice: "Allahumma taqabbal min Muhammad wa aali Muhammad wa min ummati Muhammad" (O Allah, accept from Muhammad, and the family of Muhammad, and from the Ummah of Muhammad), some scholars argue that it is permissible to offer a sacrifice on behalf of the deceased. Then, there is a difference of opinion regarding whether it is better to offer a sacrifice or to give charity on behalf of the deceased. According to the Hanbalis and most jurists, sacrifice is superior, while some jurists say that giving the price as charity is more virtuous.

The correct view is that sacrifice, in reality, like other acts of worship (fasting and prayer), is an act of worship for the living. There is no solid evidence for the exception of sacrifice. The hadith of Ali radi Allahu anhu is extremely weak, and the inference from the supplication of the Prophet sallallahu alayhi wa sallam at the time of sacrifice is a forced inference, similar to how innovators use the supplication at the graveyard to justify calling upon other than Allah. Moreover, some wordings of this narration are also as follows: "amman lam yudhhi ammati" (i.e., from my Ummah, those who could not offer a sacrifice), and its clear meaning is: "From my Ummah, whoever among the living was not able to offer a sacrifice due to lack of means, accept this sacrifice on his behalf." Furthermore, there has been no established practice in the Ummah of offering sacrifice on behalf of the deceased.

(And Allah knows best what is correct)

Note:
(In the chain, "Sharik" is weak in memory, and "Abu al-Hasna'" is unknown, and there is also severe disagreement regarding "Hansh".)
