Where can I find the Hanafite objection to the Shafi'ites, based on the principle: "Addition to the text is abrogation," in the Shafi'ites' use of the two hadiths of Aisha and Sahla as evidence for the prohibition with five sucklings?

The argument that a single suckling does not prohibit marriage because it does not satisfy hunger, and that the Sharia stipulates five sucklings, is an addition to the absolute, unquantified text. An addition to the text is tantamount to abrogation, which is impermissible. All of Aisha's hadiths are موضوع (unreliable), so they must be abandoned, and we must return to the Book of Allah (the Quran). Aisha's statement, "One suckling and two sucklings do not prohibit," is abrogated, and a single suckling now prohibits marriage. The same answer applies to her statement, "One or two breastfeeds (imlaajah) do not prohibit."
