and He also said:

“He has only forbidden to you carrion, blood, and the flesh of swine” (an-Naḥl 16:115).

After this, however, Allah went on to forbid other things, and there is no contradiction between His earlier denial of their prohibition and His later confirmation of it. But the analogy with a debt becomes clear when He makes something obligatory and then abrogates that obligation—just as He revoked the duty to give charity before holding private consultation. In such cases one holds fast to the abrogating text, not to the text that has been abrogated, just as one relies on a later acknowledgment that repayment has been made, which overrides an earlier acknowledgment of the debt itself.
