مَاتَ فُلَانٌ، رَحِمَهُ اللَّهُ
So-and-so has died; may Allah have mercy on him.
In “māta fulān, raḥimahu Allāh,” the first clause can be judged as a report, whereas the second expresses a supplication. Leaving them separate preserves the status of each and avoids turning the prayer into merely another factual item.
It illustrates complete disjunction without ambiguity when the second expression truly functions as a prayer and no misunderstanding results. With another context, the same surface words might require a different analysis.
