his argument regarding Fadak is also flawed.... Quran contradicts him... he said prophets do not leave heirs.... despite QURAN saying
And certainly We gave knowledge to Dawood and Sulaiman, and they both said: Praise be to Allah, Who has made us to excel many of His believing servants. And Sulaiman was Dawood's heir, and he said: O men! we have been taught the language of birds, and we have been given all things; most surely this is manifest grace.
Quran [27:15-16]
