Peace Mirch bhai. It is relevant.
Quran and Sunnah are the basis on which one could try to understand and follow Islam.
However the two are not at the same level. Thus the steps to use Quran and Sunnah for guidance are to use your understanding based on:
1- Quran - Explore Quran for a given topic
1a-Use the FULL context from Quran for that topic.
However if you are still confused (even though you shouldn’t be as Allah swt says that He has made Quran very easy to understand).
Then only then,
you search Sunnah for “additional” context for the topic at hand. that means a context that does not replace Quranic context but “adds” and “enhances” it.
And the very last step is that if you cannot use Quran first, Sunnah second, to fully comprehend the topic, then only then,
you go to your respective Imam and seek further guidance.
Thus it is a three step process.
As you saw the misuse/abuse of Sunnah first, and Quran second in brother Psyah’s post above,
One can easily be mislead.
See how he quoted Sahih Muslim ..Bk 1, Number 0036 First, then he quoted Quran 9:113 in order to derive a meaning that was incorrect.
Hope that answers your question.
Peace.
