Know, then, that the entire Sunnah is gathered into a single verse from that boundless sea: “Whatever the Messenger gives you, take it; and whatever he forbids you, refrain from it.” (Qur’an 59:7) Among the foremost means to realise this principle is the blessed work now before you in translation. Be aware that its composition was intended to serve two primary purposes.
First: to explain the Qur’an by the Qur’an itself. The scholars unanimously agree that the most noble and elevated form of exegesis is to interpret the Book of Allah through the Book of Allah, for none knows the meaning of Allah’s words better than Allah. Accordingly, we have bound ourselves not to clarify any passage except through one of the seven canonical readings—whether that be an alternate reading of the very verse under discussion or of another verse entirely. We do not base our explanations on anomalous readings, though we may occasionally cite one as supporting evidence for a canonical reading. Moreover, the recitations of Abū Jaʿfar, Yaʿqūb, and Khalaf are not anomalous in our estimation, nor in that of the meticulous authorities in Qur’anic recitation.
Second: to present the juristic rulings found in every verse that is specially marked for clarification in this book. For each such verse we shall set out the rulings it contains, the prophetic proofs for those rulings, and the opinions of the scholars, favouring—without bias toward any particular school or individual—the view that appears to us strongest on the basis of evidence. Our concern is with the substance of a statement, not with who voiced it; every human utterance is subject to acceptance or rejection except the speech of the Prophet, peace and blessings be upon him. Truth remains truth even if spoken by one of little standing. Have you not considered that the Queen of Sheba, though she and her people were prostrating to the sun instead of Allah, uttered a true statement that Allah Himself affirmed? Her disbelief did not prevent that confirmation. She said, as Allah relates: “Indeed, when kings enter a town, they ruin it and reduce the honoured of its people to the lowest.” (Qur’an 27:34) Thus Allah said
