Establishing Fatima's inheritance in Shi'i sources
It is mutawatir that in Shi'i sources Fatima (as) inherits Fadak from the Prophet (saw). This tawatur is proven by both explicit textual sources (nass) and corroborative evidence (qara'in). For example, consider the following reliable tradition:
Zurara narrated that Abi Ja’far (al-Baqir) (as) said: ‘Ali inherited the knowledge of Allah’s messenger and Fatima inherited his property.’
