مَا جَاءَ إِلَّا طَالِبٌ وَاحِدٌ.
Only one student came.
The sentence restricts the number of arriving students to one but does not identify that student. An analysis which inserts a particular name has exceeded the evidence of the wording.
Repair the analysis by recording the necessary meaning first and distinguishing any further inference that needs additional context. This makes restriction precise rather than speculative.
