Can you look up for me from the Salaf al-Salih if anybody has ever asked such a question—from the Sahaba, the Tabi'een, the Imams, or the Muslims and if we cannot find it and nobody asked it, why are we concerning ourselves with something that the best of people did not concern themselves with and could be (and Allah knows best) of no use to us whatsoever?
