What is the ruling on praying over the dead when we do not know whether their families are committed to prayer?

The questioner : The questioner says: Many of the funerals, especially those in the mosque.

The Shaykh : What?

The questioner : Many of the funerals, especially those in the Sacred Mosque, we pray over them without knowing whether the deceased used to pray or not? So what is the criterion in this matter?

The Shaykh : This is a strange question, my brothers. A Muslim man is brought to us and we do not pray over him? We are afraid he did not pray? This is problematic. It means that every time a funeral is brought, we have to ask his family: Did the men pray or not?
If they say he used to pray, they say, "You are suspected; your testimony is not accepted. You must bring someone from the neighbors." If the neighbors come, they say, "Perhaps you are also suspected. We will look for someone from another direction." This question, my brothers, is not applicable. Every funeral brought to us, we pray over it, whether in the Sacred Mosque or elsewhere; we pray over it. Glory be to Allah. We pray and ask for forgiveness and mercy for him, because the default for Muslims is Islam. However, if we know that the man died suddenly and we know that he did not pray, neither in the mosque nor in his home, we do not pray over him, and he has no honor. As we have said before from this minbar and others, he is not washed, not shrouded, not prayed over, and not buried with the Muslims. Rather, he is taken out to the desert, a hole is dug for him, and he is thrown in, because he has no honor. He will be gathered as mentioned in the hadith: We ask Allah for well-being. Therefore, everyone brought to us, we pray over him. Or do we not pray? We pray, my brothers, and we do not ask, "Did he pray or not?" The default for a Muslim
