Unintelligent people don’t refute what’s presented to them, they attempt to discredit the individual through personal attacks. Surah Al-Ma'idah (5:46) And We sent, following in their footsteps, Jesus, the son of Mary, confirming that which came before him in the Torah; and We gave him the Gospel, in which was guidance and light and confirming that which was before it of the Torah as guidance and instruction for the righteous.
