Qadianis disallow funeral prayers for Muslims.
Since the
Qadiani belief is that all Muslims outside their community are non-Muslims,
just like a Christian or a Hindu is a non-Muslim, the Qadiani leader Mirza Mahmud Ahmad forbade his followers from saying the funeral prayers of other Muslims. This instruction is given by him quite clearly and forcefully in his book Anwar-i Khilafat, published October 1916. At the end of the section where he deals with this question, Mirza Mahmud Ahmad writes as follows:
“Now another question remains, that is, as non-Ahmadis are deniers of the Promised Messiah, this is why funeral prayers for them must not be offered, but if a young child of a non-Ahmadi dies, why should not his funeral prayers be offered? He did not call the Promised Messiah as kafir. I ask those who raise this question, that if this argument is correct, then why are not funeral prayers offered for the children of Hindus and Christians, and how many people say their funeral prayers? The fact is that, according to the Shariah, the religion of the child is the same as the religion of the parents.
So a non-Ahmadi’s child is also a non-Ahmadi, and his funeral prayers must not be said. Then I say that as the child cannot be a sinner he does not need the funeral prayers; the child’s funeral is a prayer for his relatives, and they do not belong to us but are non-Ahmadis. This is why even the child’s funeral prayers must not be said. This leaves the question that if a man who believes Hazrat Mirza sahib to be true but has not yet taken the bai‘at, or is still thinking about joining Ahmadiyyat, and he dies in this condition, it is possible that God may not punish him. But the decisions of the Shariah are based on what is outwardly visible. So we must do the same thing in his case, and not offer funeral prayers for him.”

It is quite clear and plain from these instructions that the Qadiani belief is that all other Muslims, including the children of those Muslims and even including those
Muslims who believe in the truth of Hazrat Mirza Ghulam Ahmad but have not taken the pledge to join the Movement, are unbelievers (kafir) and non-Muslims just as people of other religions such as Hindus and Christians.
