What is the meaning of Al-Zarkashi's statement in "Al-Bahr Al-Muhit": "It is not a condition for abrogation that it be replaced by an alternative; as in the abrogation of charity in the Prophet's private counsel, and abstaining after breaking the fast during the nights of Ramadan," and what is meant by abrogation?

The meaning of Al-Zarkashi's statement in "Al-Bahr Al-Muhit" that abrogation (naskh) may not be replaced by an alternative, means that a ruling might be abrogated without another ruling replacing it. An example of this is giving charity before consulting the Messenger (peace be upon him). This ruling was abrogated in the verse that followed it without requiring anything else as an alternative. Similarly, it was obligatory for one who broke their fast to abstain for the remainder of the night, but this was abrogated without a replacement by Allah's saying: "Permitted for you on the night of the fast is sexual intercourse with your wives..." [Al-Baqarah: 187].
