ٱلَّذِينَ كَانَتْ أَعْيُنُهُمْ فِى غِطَآءٍ عَن ذِكْرِى وَكَانُوا۟ لَا يَسْتَطِيعُونَ سَمْعًا
21:43; 39:46.
Commentary:
The verse means to say that at that time worship of God will totally disappear from among the Christian peoples and love of Mammon will take the place of love of God in their hearts. They will completely forget their Creator and will attribute all their great achievements to their own skill and effort.
The words, and they could not even hear, mean that their hearts will become so much rusted and corroded that they will lose all attachment for the word of God and will refuse to listen to it.
The foregoing verses refer to the great material progress and widespread conquests of Gog and Magog—western Christian nations—and their utter disregard for God and religion. We have also been told that, elated with their political power and military glory, they will give themselves up to a life of pleasure and sin and as a result will bring the wrath of God upon themselves and their prosperity will give place to decline and degradation. Then in despair and despondency, as hinted at in Moses’ vision, they will turn to God and, having realized the error of their ways, will come back to the "junction of the two Seas" i.e. they will accept the Holy Prophet. The following prophecy of the Bible forms a befitting sequel to the account of Gog and Magog and indicates the time of their rise to power and greatness:
And when the thousand years are expired, Satan shall be loosed out of his prison. And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle; the number of whom is as the sand of the sea (Revelation 20:7-8).
By "the thousand years" are meant the thousand years of the Hijrah—Migration of the Holy Prophet to Medina in 622 A.D. The above passage along with chapters 38 and 39 of Ezekiel makes it quite clear that the rise of Gog and Magog was to have begun in the 17th century A.D. and to have reached its zenith in our own time.
The account of Dhul-Qarnain will remain incomplete unless the reason is given as to why it has been assigned such a prominent place in the Quran, when as a fact of history does not appear directly to concern us nor does its narration benefit us materially or spiritually. In fact, it is more for its spiritual than for its historical importance that the story of Dhul-Qarnain has been given so large a space in the Holy Book. The Quran is not a book of history. The stories of past Prophets and other historical incidents have not been mentioned in it to acquaint us with events which took place in the remote past. They are so many prophecies about future events. Some of these prophecies have already been fulfilled in the person of the Holy Prophet while others await fulfilment in some future time. The account of Dhul-Qarnain, like other similar Quranic accounts, embodies a great prophecy which has been fulfilled in the person of Ahmad, the Holy Founder of the Ahmadiyya Movement. Ahmed was the Dhul-Qarnain of our age. Whereas the Quranic account of Dhul-Qarnain historically applies to the great Persian monarch Cyrus, spiritually it applies to Ahmad. Thus besides its historical value the story is pregnant with great spiritual import. It implies a great prophecy to the effect that, just as in the 6th century B.C. Cyrus saved Persia from the depredatory raids of Gog and Magog, by erecting a barrier of brick and stone in their way, another Dhul-Qarnain will save the soul and spirit of mankind, from the devastating moral assaults of Christian nations of the West who are the descendants of Gog and Magog. He will accomplish his great and noble task by the help of divine knowledge and the signs that God will show at his hands. The nature of the work entrusted to both these Dhul-Qarnains bears a striking likeness to each other, only the one was in the mundane sphere, the other in the spiritual. The Prophet Ahmad possessed many physical and spiritual resemblances with the great Cyrus. Like Cyrus, he was called the Messiah and like he, was of Persian origin. Cyrus was Dhul-Qarnain in the sense that he was the ruler of the double Medo-Persian Empire and Ahmad (1835--1908) was Dhul-Qarnain in the sense that he saw the beginning of two centuries of several eras (Qarn meaning a century).
