Almuntakhab Fi Tafsir Alquran Alkarim

The Day shall come when We put or set the mountains in motion and you see the earth bare of the natural objects it once had, and We will have thronged them -all people- to judgement, leaving not one behind

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(18:47) The only thing, for which you should prepare, is the Day when We will set the mountains in motion, *42 and when you will find the Earth quite naked, *43 and We will muster together all human beings in a way as to leave none at all behind, *44

And [warn of] the Day when We will remove the mountains and meaning

*42) The mountains will begin to move about like clouds when the gravitation of the earth shall be brought to an end. The Qur'an has described the same thing in XXVII: 88 in this way: "When you see the mountains, you consider them to be firmly fixed, but they shall be floating about like clouds at that time."
*43) "You will find the Earth quite naked": You will find no vegetation and no building on it and it will become a barren plain. It is the same thing that has been stated in v. 8 of this Chapter.
*44) That is, "We will muster together every human being from the first Man, Adam, to the last one born in the last moment of the Day of Resurrection: even that child which had breathed the first breath after its birth, shall be resurrected and all shall be mustered at one and the same tune."
 

And [warn of] the Day when We will remove the mountains and meaning in Urdu

فکر اُس دن کی ہونی چاہیے جب کہ ہم پہاڑوں کو چلائیں گے، اور تم زمین کو بالکل برہنہ پاؤ گے، اور ہم تمام انسانوں کو اس طرح گھیر کر جمع کریں گے کہ (اگلوں پچھلوں میں سے) ایک بھی نہ چھوٹے گا
