Or ,perhaps you follow your own understanding after checking and studying Qoran yourself. Of course one can also study what others are saying, like does it fit with Qoran?
At the end of the day, it should be your own reasoning/understanding where you are satisfied that you have used your "eyes, ears and brain" without bias or pressure and with honesty and sincerity to follow GOD s message ,if you believe in GOD.
GOD will try your true conviction and effort . And it will be between you and GOD in the end.
Always stay with what you understand best from your own checking. Do not rush ,even if your doubts grow.
GOD bless you.
Peace.
