Hujjiyat ul Qur’aan (Its proof and validity)
The Qur’aan is a book which is Arabic in terms of language and style, which Muhammad (saw) came with. It can therefore either have come from the Arabs, or from Muhammad or it could have come from Allah Ta’Aalaa. It is not possible for it to have come from any other than these three due to it being Arabic in language and style.
As for it having come from the Arabs then this is false and invalid because the Qur’aan challenged them to come with and reproduce the like of it, indeed just one Soorah like it. Allah Ta’Aalaa said:
Or do they say [about the Prophet]: "He invented it?" Say: "Then bring forth a Soorah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful" (Yousuf 38).
It is therefore not from the Arabs because they were incapable and did not have the ability to reproduce the like of it or a Soorah like it. Their inability was established and verified and they still remain incapable of bringing the like of it.
As for it having originally come from Muhammad (saw) then this is also false and invalid because Muhammad (saw) was an Arab and whatever the level of his genius or eloquence, he was still one from amongst his society. As long as the Arabs were not able to bring the like of it and as long as Muhammad (saw) is one of them, then what applies to them also applies to him. In addition to that Muhammad (saw) has Ahaadeeth (speech) that has reached us by way of Tawaatur (definite transmission) like the Hadeeth: “Whosoever lies about me deliberately then let him take his seat in the fire” (Al-Bukhaari and Muslim). If this Hadeeth or any Hadeeth is compared to an Aayah of the Qur’aan no resemblance in style can be found between them.
The Arabs themselves did not make the claim that the Qur’aan was the speech of Muhammad (saw) but rather one of their claims was that a Christian youth called Jabar would bring it to him. Allah Ta’Aalaa then refuted them by His Qawl:
And We certainly know that they say, "It is only a human being who teaches the Prophet." The tongue of the one they refer to is foreign, and this Qur'an is [in] a clear Arabic language (An-Nahl 103).
The Qur’aan is therefore not originally from Muhammad (saw).
The Qur’aan must therefore definitely be the Kalaam (speech) of Allah Ta’Aalaa. It is a miracle for Muhammad (saw) to indicate and guide to the fact that he is a Nabi and Rasool sent by Allah Ta’Aalaa.
This represents the rational and intellectual (‘Aqliy) proof and evidence in respect to the Qur’aan being from Allah and it has been established and affirmed by Tawaatur (definite transmission) that it is the same Qur’aan that Allah Ta’Aalaa revealed upon Muhammad (saw).
Allah Ta’Aalaa has addressed mankind in this Qur’aan in a number of Aayaat demanding that they follow that which was revealed in it. Allah Ta’Aalaa said:
And verily, this is my Straight Path, so follow it, and do not follow (other) paths, for they will separate you away from His Path (Al-An’aam 153).
And He Ta’Aalaa demanded that they rule and judge by what He had revealed in it:
And so judge between them by what Allah has revealed and do not follow their desires and beware of them lest they seduce away from some of that which Allah has sent down to you (Al-Maa’idah 49).
And He Ta’Aalaa said:
And whosoever does not judge by what Allah has revealed then they are the disbelievers (Al-Maa’idah 44).
The Qur’aan is therefore a Hujjah (proof and argument) over mankind and its Ahkaam are obligatory to be followed.
