لَيْتَ لِي مَالًا أُنْفِقْهُ
If only I had money; I would spend it.
The wish is not formally a conditional, but obtaining money is a meaningful prerequisite for spending it. The explanatory reconstruction is in urzaqhu unfiqhu: if I am given it, I spend it.
The point is the dependency of the second action on the content of the wish. Such dependency makes a request–response construction intelligible without turning every wish into an explicit condition.
