Before them is Hell, and what they had earned will not avail them at all nor what they had taken besides Allāh as allies. And they will have a great punishment.
The Description of the Sinful Liar and His Requital
Allah the Exalted says,
تِلْكَ آيَـتُ اللَّهِ
(These are the Ayat of Allah) -- in reference to the Qur'an with the proofs and evidences that it contains,
نَتْلُوهَا عَلَيْكَ بِالْحَقِّ
(which We recite to you with truth.) for they contain the truth from the Truth (i.e., Allah). Therefore, if they do not believe in Allah's Ayat nor abide by them, what speech after Allah and His Ayat will they then believe in Allah said next,
وَيْلٌ لِّكُلِّ أَفَّاكٍ أَثِيمٍ
(Woe to every sinful liar.) who lies in his speech, often swears, who is worthless, commits and utters sinful acts and statements, and disbelieves in Allah's Ayat,
مِّن وَرَائِهِمْ جَهَنَّمُ "In front of them, there is Jahannam...45:10" The word وَرَاءِ war' in Arabic is mostly used in the sense of "behind" and occasionally used in the sense of "front". Most commentators have taken the word in this context to mean ` front' and we have translated it accordingly. However, some of the commentators have taken it in this context to mean ` back/behind' and interpreted it to mean that those who are living in haughtiness and arrogance, the fire of Hell is trailing behind/after them. (Qurtubi).
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 6–10
To say that the Quran is a revelation from the All-Powerful and Wise God amounts to giving on His behalf a definite standard on the basis of which its veracity can be demonstrated. Its divine origin means, moreover, that it will prove to be unassailable. The Quran will, in any case, prevail over its opponents. This statement was made in the Makkan period. At that time, circumstances were entirely against the Quran. But later history has most wonderfully testified to the veracity of this statement. The call given by the Quran met with the greatest success in history. Similarly, the notion of revelation from God the Omniscient and Almighty implies that all its contents must be based on knowledge and wisdom. The Quran was revealed before the age of science. But now, even in this age of science nothing mentioned in the Quran has been proved irrational. Furthermore, all the things in the Universe spread out far and near are testimonies to the truth of the Quran’s message. However, this testimony will be valid only for one who possesses a receptive and believing mind; who is capable of grasping the real meaning of such matters as are expressed in the language of signs.
