إِنَّ الْكَذِبَ فُجُورٌ، وَإِنَّ الْفُجُورَ يَهْدِي إِلَى النَّارِ
Lying is wickedness, and wickedness leads to the Fire.
Source: مسلم
الْكَذِبَ is lying; فُجُورٌ is grave wrongdoing or moral transgression; النَّارِ is the Fire. A lie can be followed by concealment, broken trust, and further wrongdoing.
In إِنَّ الْكَذِبَ فُجُورٌ, الْكَذِبَ is the noun of inna and فُجُورٌ its predicate. وَإِنَّ الْفُجُورَ يَهْدِي parallels the preceding hadith grammatically, but the moral destination is opposite.
This is a warning about the dangerous trajectory of lying, not a human verdict on the final destiny of a named individual.
