وَالشَّفَاعَةُ الَّتِي ادَّخَرَهَا لَهُمْ حَقٌّ كَمَا رُوِيَ فِي الْأَخْبَارِ
The intercession reserved for the Prophet ﷺ is true, as transmitted in the reports.
Clause structure: In al-shafāʿatu allatī iddakharahā lahum, allatī is a relative pronoun followed by its clause; the pronoun hā refers back to intercession.
Meaning and inference: The relative clause identifies the intercession reserved for the Prophet ﷺ; that intercession is affirmed as true.
Limit of inference: Without tracking the pronoun, a reader can confuse what is reserved with whom it is reserved for.
