How can one respond to the شبهات (misconceptions/specious arguments) of the Quranists regarding the contradiction of the hadith of Al-Wa'idah and Al-Maw'udah (the living burier of infant girls and the buried infant girl) with the Qur'an, the authenticity of the hadith of the transformed mouse, and the absence of Ahadith about the Dajjal in the Qur'an?

Denying the established Sunnah, or what has been transmitted consecutively from it, is major disbelief. The hadith "The female burier and the buried female are in the Hellfire" can be interpreted to mean that the buried female had reached the age of accountability, or that the hadith contradicts the foundational Quranic principle, "And We would not punish until We had sent a messenger," and Allah wrongs no one.
