The Quran is a fundamental source of Islamic knowledge. The Hadith which includes the sayings and recorded actions of the Prophet (ﷺ) among other things, closely follow the Quran as the second fundamental source of Islamic knowledge. Early scholars have done a great service to Islam to meticulously collect and authenticate the Hadith. They actually developed a science of Hadith authentication that is not found in any other literature religious or otherwise, specially from that long ago. Furthermore, early scholars also wrote Tafseer (exegesis or the explanation) of the Quran. Classical Tafseer also rely on the Hadith and Athaar (sayings of the companions of the Prophet (ﷺ).
In other words, simply picking up an Oxford printing of the translation of the Quran into English by an Western Orientalist author does not convey the real meaning of the Quran to anyone.
To understand and interpret the message of the Quran accurately, one has to find out what the Arabic words meant (i.e. the linguistic and cultural context of the people of Quraish tribe in Mecca at that time), the reasons of revelation (the historical context within which the verses were revealed), what the Prophet (ﷺ) said about the revelation and how the companions of the Prophet (ﷺ) understood it (recorded in the books of Hadith) and how the early scholars explained it (recorded in the books of classical Tafseer).
Trying to interpret the Quran any other way would result in misinterpretations. It makes no sense to base our understanding of the Quran on the explanation of people who neither know the Arabic language nor rely on the classical Tafseer and authentic Hadith collections. Yet we see a lot of people doing just that. May Allah protect us all from misguidance.
In the next chapter, I’ll write in more detail about the importance of relying on Hadith to arrive at the correct understanding of the Quran and hence getting an accurate picture of Islam as a whole.
And Allah knows best.
