In one of the answers to your questions, you mentioned the prevailing madhabi principle of only taking 'muttawatir' issues into aqeedah and not ahad.

All the basic Aqaaid of Islam are mentioned in the Qur'aan itself, any need for clarification being sufficed by the Ahaadith Mutaawaatir. Thus, leaving no real need for admission of Khabar Ahad matters of Aqaaid.

This is aside from the fact that Khabar Ahad, containing elements of doubt, cannot be used to define principles upon which the very fundamentals of Imaan (belief) are based. Furthermore, Khabar Ahad, being open to difference of opinion, if admitted into such matters could weaken the very foundations of Aqaaid.
