What is the meaning of "An-Nasi'" in the verse: "Indeed, An-Nasi' is an increase in disbelief"?

The "Nasi'" (postponement) mentioned in the verse: (Indeed, the postponement [of a sacred month] is an increase in disbelief) refers to what the Arabs used to do before Islam, which was altering and permitting the sacred months. They would permit fighting in the sacred months if they needed to, and instead, they would sanctify another month, due to the frequency of their raids and their need for combat.
