Since this issue came to our knowledge, our duty as Muslims who must give sincere advice for the sake of Allah and His servants obliges us to clarify the Islamic ruling on a person who impugns the Qur'an claiming that it contains contradictions and some myths, and on a person who calumniates the Prophet (peace be upon him) in any way. Jealousy and anger for the sake of Allah impel us to do so, as we are dutybound to support His Glorious Book and His Honorable Messenger and to discharge some of our obligations toward Him. Our aim here is to clarify the ruling on whoever disparages the Book of Allah or His Messenger; whether the doer declares denial of or Tawbah (repentance to Allah) from this act or not.
The Book of Allah, Sunnah of His Messenger and Ijma' (consensus of scholars) testify that the Book of Allah is a perfectly precise book and that it is the Word of Allah revealed by Him. This Book is free from any superstitions or lies. The mentioned sources of evidence affirm the necessity of showing veneration to and support of the Prophet (peace be upon him). They also affirm that casting aspersions on the Book of Allah or His Messenger is regarded as major Kufr (disbelief) and Riddah (apostasy). We here present to the noble reader the clarification of this matter:
In Surah Yunus, Allah (Exalted be He) says, AlifLâmRâ. [These letters are one of the miracles of the Qur'ân, and none but Allâh (Alone) knows their meanings]. These are the Verses of the Book (the Qur'ân) AlHakîm In the beginning of Surah Hud, He says, AlifLâmRâ. [These letters are one of the miracles of the Qur'ân and none but Allâh (Alone) knows their meanings]. (This is) a Book, the Verses whereof are perfected (in every sphere of knowledge), and then explained in detail from One (Allâh) Who is AllWise WellAcquainted (with all things). In Surah Luqman, He (Glorified and Exalted be He) says, AlifLâmMîm. [These letters are one of the miracles of the Qur'ân, and none but Allâh (Alone) knows their meanings]. These are Verses of the Wise Book (the Qur'ân).
The scholars of Tafsir (exegesis of the meanings of the Qur'an) commented that these Ayahs show that the Qur'an, whose wording and meanings are precise, contains just rulings, truthful stories and upright legislation.
It is also the judge between people in their disputes. Allah (may He be Praised) says, Mankind were one community and Allâh sent Prophets with glad tidings and warnings, and with them He sent down the Scripture in truth to judge between people in matters wherein they differed. and: Have you not seen those who have been given a portion of the Scripture? They are being invited to the Book of Allâh to settle their dispute .
Consequently, how can a book whose content is full of contradictions and myths be the same one whose wording and meanings are precise and which is used to judge between people?! How can it be a reliable and precise book if the Messenger who brought such a book is a naïve person who cannot differentiate between the truth and superstition?! Based on this, a person who claims that the Qur'an has contradictions and myths or that the Messenger (peace be upon him) is naïve, is disparaging the Book of Allah, denying the Revelations of Allah, defaming the Prophet (peace be upon him) and undermining the integrity of his mind. Any Muslim who makes such a claim is regarded as a Kafir (disbeliever) and Murtad (apostate from Islam).
In the beginning of Surah Yusuf, Allah (may He be Praised) says, AlifLâmRâ. [These letters are one of the miracles of the Qur'ân, and none but Allâh (Alone) knows their meanings]. These are the Verses of the Clear Book (the Qur'ân that makes clear the legal and illegal things, laws, a guidance and a blessing). Verily, We have sent it down as an Arabic Qur'ân in order that you may understand. We relate unto you (Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭ ﺳﻠﻢ) the best of stories through Our Revelations unto you, of this Qur'ân. And before this (i.e. before the coming of Divine Revelation to you), you were among those who knew nothing about it (the Qur'ân). and in Surah AlZumar He (Exalted be He) says, Allâh has sent down the Best Statement, a Book (this Qur'ân), its parts resembling each other (in goodness and truth) (and) oftrepeated.
The people of knowledge explain the meaning of the phrase "resembling each other" saying that the parts of this Book are similar to one another and affirm one another. How can a book which is the best of speech and tells the best of stories contains contradictions or superstitions?! Glory to You, O Allah! This is a great slander.
It was authentically reported from the Prophet (peace be upon him) that he used to say in his Khutbahs (sermons), "Ama Ba'd (Now then)! The best of speech is the Book of Allah, the best of guidance is the guidance of Muhammad (peace be upon him)."
Anyone who casts the aforesaid aspersions on the Qur'an or invents other lies is contradicting Allah's Words Who has described His Book as the best speech and best of narratives.
