Shaykhul Islaam Thaani Ibn Qayyim al-Jawzeeyah 751 AH (may Allah have mercy on him) said in his poem “al-Kaafiyah ash-Shaafiyah”

العلم قال الله قال رسوله

قال الصحابة هم أولو العرفان

ما العلم نصبك للخلاف سفاهة

بين الرسول و بين رأي فلان

“Knowledge is what Allah, His messenger, and the companions said. They are the people of gratitude

Knowledge is not taking hadith of the messenger and comparing it to another person’s view.”
