Surah Al-Anbya, Ayah 96

Those who have been destroyed, will never return to this World.

وَحَرَامٌ عَلَى قَرْيَةٍ

(And a ban is laid on every town) Ibn `Abbas said, "it is enforced", i.e., it has been decreed that the people of each township that has been destroyed will never return to this world before the Day of Resurrection, as is reported clearly through other narrations from Ibn `Abbas, Abu Ja`far Al-Baqir, Qatadah and others.

Ya'juj and Ma'juj

حَتَّى إِذَا فُتِحَتْ يَأْجُوجُ وَمَأْجُوجُ

(Until, when Ya`juj and Ma`juj are let loose,) We have already mentioned that they are from the progeny of Adam, upon him be peace; they are also descents of Nuh through his son Yafith (Japheth), who was the father of the Turks, Turk referring to the group of them who were left behind the barrier which was built by Dhul-Qarnayn. Allah says:

حَتَّىٰ إِذَا فُتِحَتْ يَأْجُوجُ وَمَأْجُوجُ وَهُم مِّن كُلِّ حَدَبٍ يَنسِلُونَ (Until when the Ya'juj and Ma'juj (Gog and Magog) are released, while they run down from every height - 21:96.) In the previous verse it was said that those who died in a state of unbelief will never return to this world. The phrase "until the Ya'juj and Ma'juj appear", really means that such people will never return, because the appearance of Ya'juj and Ma'juj will be a sign of near approach of the Dooms Day.

It is reported in Sahih of Muslim through Sayyidna Hudhaifah ؓ that he and some other Sahabah ؓ ، were in the midst of a discussion when the Holy Prophet ﷺ came to them and enquired as to what were they deliberating. They replied that they were discussing about the Qiyamah (Dooms Day). Thereupon he said that Qiyamah will occur only after ten signs have become manifest, and the appearance of Ya'juj and Ma'juj will be one of them.

Here the word فُتِحَت (released) is used for Ya'juj Ma'juj which means to let loose, which suggests that until the appointed time they will remain under restraint and confined behind some barrier from which they will be released when Doomsday is near. It is evident from the Holy Qur'an that this restraint is the wall made by Dhulqarnain which will disappear near the Qiyamah. Ya'juj and Ma’ juj and Dhulqarnain have been described in fair detail in Surah Al-Kahf, to which the reader may refer.

مِّن كُلِّ حَدَبٍ يَنسِلُونَ (while they run down from every height - 21:96) The word حَدَبٍ 'means an elevated place which may be a mountain or just a lump in the ground. We have also seen in Surah Al-Kahf that the place where Ya’ juj and Ma'juj have been confined is somewhere beyond the northern mountains. So when they will come out, they will be seen rushing down the mountain sides in their hordes.

God has sent all prophets with the same religion, namely, one according to which the one and only God should be one’s God and that He alone should be worshipped. Had people been steadfast in this original religion, all of them would have continued as one Community (ummah). But, people on their own started entering into disputes and thus concocted different versions of the same religion. Individuals exercised their ‘right’ to choose whatever religion best suited their interests. Thus one religion came to be divided into many religions. To God, faith and deeds have importance only when they signify true realization of Him and true obedience to Him. Anything other than these will not be appreciated by God, however much the individuals themselves may attach value to them.
