It is not permissible for that one who forgot to let the forgotten [knowledge] be heard except from an expert scholar (Alim Khabir) after another interval, following the drinking of the Secret (al-Sar) for him and the Suspension (al-Ta'liq) for the new Hearing (Sama'), but without gradual progression (Tadrij), because he had already been initiated. Thus, it is permissible for him, as we mentioned, in a single night. His hearing from his biological (Tabi'i) son is permissible, but its method is invalid (Fasidah).

It is not permissible for the biological brother to let his biological brother, uncle, maternal uncle, or nephew hear [the knowledge].

It is not permissible for a person to let his biological paternal uncle or biological maternal uncle hear [it].

It is not permissible for one who instructed (Faqqaha) a person, who then forgot the Instruction (Fiqh), to hear [the knowledge again] from the one who [originally] instructed him¹, because he is his master and his foster-father (Murdi').
