لَا أَمْلِكُ بُلْغَةً
I possess not even the minimum provisions needed to get by.
بُلْغَة refers to an amount sufficient for a basic need or for making it through a stage of a journey. It does not mean luxury or ample wealth; it suggests bare subsistence.
لا أملك means “I do not possess.” His situation is now more serious than an empty bag: he lacks even the essentials.
