Question:
Does any scholar ever say that we can not take into aqeedah an ahad hadith?
Answer:
Most of the fuqaha‘ and Ahl al-Hadith say it from the time of the Salaf to ours with the exception of the likes of Ibn al-Qayyim and al-Albani. This does not mean that one is free to reject any and all lone-narrator reports as not binding! On the contrary, as we said, they are binding, but are not retained to define the `aqidah of every Muslim for to deny any aspect of the latter is kufr whereas as we said the denial of any ahad hadith is only fisq.
