How can the view that considers one who abandons prayer to be an infidel be reconciled with the fact that the Negus is among the people of Paradise, given that there is a narration stating that he did not pray?

"Abandoning prayer is an act of disbelief according to the consensus transmitted from the Companions, the Tabi'in, and the majority of the Salaf. However, the Negus did not abandon prayer; rather, he was a Muslim, righteous, and powerful among his people. This is evidenced by the Prophet's prayer over him, his testimony to his righteousness, his protection of the Muslim emigrants, his rejection of gifts from the polytheists of Quraish, and his refusal to pay tribute to Heraclius after embracing Islam. The claim that he did not perform the five daily prayers is a weak assertion, not attributed to any scholar, and the interpretation that he was unable to perform them is invalid given the established evidence of his strength and power."
