It is the truth from your Lord…” Then...
It is the truth from your Lord…” Then, the Holy Qur’an refers to the aim of its revelation, when it says: “…that you may warn a people to whom no warner came before you, that haply they may be guided aright.” The invitation of the Prophet of Islam (S) is both ‘glad tidings’ and ‘warning’, and more than being a warner, the Prophet of Islam (S) is a giver of glad tidings, yet confronting a misguided and obstinate group, he (S) should emphasize rather on ‘warning’.
The sentence which says: “…it is the truth from your Lord…” is again a hint to this fact that the proof of its legitimacy is seen inside of it. The sentence: “…That haply they may be guided aright” points to this fact that the Holy Qur’an leads you to the right path but the final decision, however, must be made by man himself. By the way, the “ people to whom no warner came ” were Quraysh because there had not been sent a prophet for them before the Prophet of Allah, Muhammad (S).
Some of the commentators have said the objective meaning of this sentence is the intermission time and its purpose is the length of the time between Jesus (as) and the advent of the last Prophet (S). For more explanation you may refer to commentary books entitled: Tafsir-us-Safi, Jawami‘-ul-Jami‘, Majma‘-ul-Bayan, Manhaj-us-Sadighin, and Atyab-ul-Bayan.
“Allah is He Who created the heavens and the earth and what is between them in six Days then He established Himself on ‘Arsh (the Throne of authority), for you there is none besides Him of a guardian, nor any intercessor; will you not then receive admonition?” In order to wipe out polytheism, the eternal power of Allah and the creation of heavens and earth must be spoken of.
So, next to the statement of the greatness of the Qur’an and the Messengerhood of the Prophet (S), this verse refers to one of the most important bases of the Islamic beliefs, i.e. Monotheism and negation of polytheism.
