You do not have a philosophical Guidance of Qur’an to establish the true knowledge of the Qur’an. Neither do the present-day Jews take any Guidance from the Torah to interpret God’s Word in the Torah.
You use the Arabic language, your human knowledge of science and creation, the knowledge of people like Parwez and company, etc, to believe what you think is the true knowledge of the Qur’an.
The Jews use the Talmud.
I am Guided by the Creeds of Abraham and the worldview teachings of Tawhid (unity and universality), which are found in the Qur’an.
These teachings of the Qur’an complement one another to give a very precise knowledge of the Qur’an and to convince what are the correct teachings of the Qur’an.
