Surah Al-Kahf 18:98

The Barrier restrains Them, but It will be breached when the Hour draws nigh

Allah tells us that Ya'juj and Ma'juj could not climb over the barrier or penetrate its lower portion. Varying forms of the verb are used here in the Arabic text to reflect the difficulty of the action referred to.

(So they (Ya'juj and Ma'juj) could not scale it or dig through it.) This indicates that they could not penetrate it or dig through it. Imam Ahmad recorded that Zaynab bint Jahsh, the wife of the Prophet said, "The Prophet woke from sleep, and he was red in the face. He said,

(La ilaha illallah! Woe to the Arabs from the evil that has approached (them). Today a hole has been opened in the barrier of Ya'juj and Ma'juj like this.) and he made a circle with his index finger and thumb. I Zaynab said, `O Messenger of Allah, will we be destroyed even though there will be righteous people among us' He said:

(Yes, if evil increases.)" This is a Sahih Hadith, both Al-Bukhari and Muslim recorded it.

((Dhul-Qarnayn) said: "This is a mercy from my Lord...") meaning, after it was built by Dhul-Qarnayn.

(He said: This is a mercy from my Lord) for the people, when he placed a barrier between them and Ya'juj and Ma'juj, to stop them from spreading evil and corruption on earth.

(but when the promise of my Lord comes) means, when the true promise comes

(He shall Dakka' it down to the ground.) means, will make it flat. The Arabs use Dakka' to describe a female camel whose back is flat and has no hump. And Allah says:

(So when his Lord appeared to the mountain, He made it Dakkan) 7:143 meaning, level to the ground.

(And the promise of my Lord is ever true.) means, it will come to pass without a doubt.

(We shall leave some of them) meaning mankind, on that day, the day when the barrier will be breached and these people (Ya'juj and Ma'juj) will come out surging over mankind to destroy their wealth and property.

(We shall leave some of them to surge like waves on one another;) As-Suddi said: "That is when they emerge upon the people." All of this will happen before the Day of Resurrection and after the Dajjal, as we will explain when discussing the Ayat:

(Until, when Ya'juj and Ma'juj are let loose, and they swoop down from every Hadab. And the true promise shall draw near...) 21:96-97

(and As-Sur will be blown.) As-Sur, as explained in the Hadith, is a horn that is blown into. The one who will blow into it is (the angel) Israfil, peace be upon him, as has been explained in the Hadith quoted at length above, and there are many Hadiths on this topic. According to a Hadith narrated from `Atiyah from Ibn `Abbas and Abu Sa`id, and attributed to the Prophet ,

(How can I relax when the one with the Horn has put the Horn in his mouth and has knelt down, listening out for the command to be given to him) They said, "What should we say" He said:

(Say: "Allah is Sufficient for us and the best Disposer of affairs, in Allah have we put our trust.")

(and We shall collect them (the creatures) all together.) means, `We shall bring them all together for Reckoning.'

(Say: "(Yes) verily, those of old, and those of later times. All will surely be gathered together for appointed meeting of a known Day.) 56:49-50

(and we shall gather them all together so as to leave not one of them behind.) 18:47

Selanjutnya Zulkarnain berkata, "Benteng ini adalah merupakan rahmat karunia dari Tuhanku kepada hamba-Nya, karenanya ia menjadi benteng yang kokoh yang menjaga mereka dari serbuan Yakjuj dan Makjuj. Tetapi apabila telah datang janji Tuhanku tentang keluarnya mereka dari belakang benteng, maka Dia akan menjadikannya hancur luluh lantak rata dengan tanah karena Allah memberi kuasa kepada suatu kaum untuk menghancurkannya, dan janji Tuhanku itu adalah benar tidak dapat diragukan.

Menurut ahli sejarah, ucapan Zulkarnain ini terbukti dengan kasus munculnya raja Jengis Khan yang telah membuat kerusakan di muka bumi dari Timur sampai ke Barat dan mengadakan penyerangan yang menghancurkan benteng besi dan kerajaan Islam di Baghdad. Adapun sebabnya raja Jengis Khan ini mengadakan penyerbuan ke negeri Baghdad, oleh karena Sultan Khuwarazmi dari Bani Saljuk telah membunuh beberapa utusan dan pedagang-pedagang yang diutus dari negerinya. Harta benda mereka dirampas dan diadakan pula serbuan-serbuan ke tapal batas negerinya sehingga menimbulkan kemarahan raja Jengis Khan. Lalu ia menulis surat kepada Sultan Bagdad dengan kata-kata yang pedas sebagai berikut, "Mengapa kamu berani membunuh sahabat-sahabatku dan merampas harta benda perniagaanku. Apakah kamu membangunkan singa yang sedang tidur dan menimbulkan kejahatan-kejahatan yang tersembunyi."

Tidakkah Nabimu memberikan wasiat kepadamu agar tidak berbuat aniaya. Oleh karena itu tinggalkanlah bangsa Turki selagi mereka tidak mengganggu kamu. Mengapa kamu sakiti tetanggamu padahal Nabimu sendiri telah berwasiat untuk menghormati tetangga. Dan inilah wasiatku kepadamu, "Peliharalah baik-baik dan pertimbangkanlah kebijaksanaanmu sebelum timbulnya rasa dendam dan sebelum terbukanya benteng besi. Dan Allah pasti akan menolong setiap orang yang dianiaya, karena itu tunggulah kedatangan Yakjuj dan Makjuj yang akan turun dari tiap-tiap tempat yang tinggi."

"Dari Umu Habibah ra dari Zainab binti Jahsyin ra, bahwa Rasulullah saw pada suatu hari masuk ke rumah istrinya, Siti Zaenab bint Jahsy dan dengan terkejut beliau mengatakan, "La ilaha illallah, celakalah bagi orang Arab dari suatu kejahatan yang telah mendekat, hari ini terbuka dari Benteng Yakjuj dan Makjuj lubang besar seperti ini." Dan beliau melingkarkan ibu jarinya dengan jari telunjuknya. Lalu Zaenab bertanya, "Ya Rasulullah apakah kami akan binasa padahal di kalangan kami terdapat banyak orang-orang yang saleh." Beliau menjawab, "Ya, apabila kejahatan sudah banyak jumlahnya." (Riwayat al-Bukhari)

Sejak hari itu lubang di dalam benteng semakin lama semakin besar. Pada abad ke-7 Hijri, datanglah tentara raja Jengis Khan menyerbu dan menimbulkan berbagai kerusakan di muka bumi terutama di negeri Baghdad.
