Is the funeral prayer performed for one who died by burning or drowning and whose body was not found?

Question:
May Allah reward you. And in his other question, he asks: Is the funeral prayer performed for one who died in a fire and was charred, and likewise for one who drowned and whose body was not found?

Answer:
As for the martyrs other than those in battle, they are called martyrs in the Hereafter, but in this world they are dead. They are treated as the dead are treated: they are washed, shrouded, and the funeral prayer is performed over them. As for the martyrs of battle, they are not washed, not shrouded, and the funeral prayer is not performed over them, as stated in the Prophetic Sunnah. Yes. As for the other martyrs—the one stung, the one who dies of a stomach ailment, the one burned, the one crushed, and others—these are martyrs if they are Muslims, but they are treated as the dead are treated.
If nothing of his body is found, the funeral prayer is not performed over him. The prayer is performed over the body, or over part of it if part of it is found. Yes.
