Al-Allaamah Ahmad Al-Ajmi [May Allah have mercy on him] said:

In order to be acquainted with the straight path, one has to return to the Quran and Sunnah, and that which has been affirmed in the Seerah of the Prophet ﷺ, the actions of the rightly guided Caliphs and rightly guided scholars who came after them. And this cannot be known except from the Hadith. And by way of it, one will become acquainted with understanding in the religion and the rulings of the Sharee’ah, the actions of the Sahaabah and their creed, the actions of the early rightly guided Imaams- those who [transmitted and based their lives on] Hadeeth and were people of sound creed. Therefore, it is obligated on you to [adhere] to that; strive in [this path] and do everything within your capability to be acquainted with it.”
