Is the intended meaning of abrogation (naskh) in His, the Almighty’s, saying, "Whatever verse We abrogate" (Quran 2:106), the abrogation of laws whenever wisdom necessitates it, and that the mention of "verse" (ayah) is a mention of the part while intending the whole?

Allah Almighty abrogated whatever He willed of legislations, according to His wisdom. The legislation of Islam abrogated all other legislations because prophethood was sealed with it, and Ibn Hajar concurred on this. The meaning of His Almighty saying: "Whatever verse We abrogate or cause to be forgotten, We bring forth [one] better than it or similar to it" is the transfer of the ruling of a verse to another, so abrogation does not apply to narratives. This verse was revealed to refute the polytheists and Jews who impugned the Quran's contradictions, such as the abrogation of the initial verses of Surat Al-Muzzammil by the verses of alleviation at its end, which transformed the night vigil from an obligation to a voluntary act.
