Surah 30. Ar-Rum
Ayah 25 - 27
25 وَمِنْ ءَايَـٰتِهِۦٓ أَن تَقُومَ ٱلسَّمَآءُ وَٱلْأَرْضُ بِأَمْرِهِۦ ۚ ثُمَّ إِذَا دَعَاكُمْ دَعْوَةً مِّنَ ٱلْأَرْضِ إِذَآ أَنتُمْ تَخْرُجُونَ
26 وَلَهُۥ مَن فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۖ كُلٌّ لَّهُۥ قَـٰنِتُونَ
27 وَهُوَ ٱلَّذِى يَبْدَؤُا۟ ٱلْخَلْقَ ثُمَّ يُعِيدُهُۥ وَهُوَ أَهْوَنُ عَلَيْهِ ۚ وَلَهُ ٱلْمَثَلُ ٱلْأَعْلَىٰ فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ وَهُوَ ٱلْعَزِيزُ ٱلْحَكِيمُ
[25-27] And of his Signs is this that the Heaven and the Earth stand firm by His Command,36 then as soon as He summons you out of the earth, you shall come out at one call.37 Whoever exist in the heavens and the earth, are His servants; all are obedient to Him. He it is Who originates the creation; then He alone will repeat it, and this is easier for Him.38 His are the most exalted attributes in the heavens and the earth, and He is the All-Mighty, the All-Wise.
36That is, "Not only have they come into being by His Command, but their continuous existence and the functioning in them of a grand workshop of life constantly is also due to His Command. If His Command does not sustain them even for a moment, the entire system should break down at once."
37That is, "It is not at all difficult for the Creator and Controller of the universe to raise you back to life; for this He will have to make no preparation. His one call will be enough to raise and muster together from every corner of the earth all human beings who have been born since the beginning of creation and will be born in the future.
38That is, "If it was not difficult for Him to create you in the first instance, how can it be difficult for Him to re-create you? Your first creation was not difficult for Him because your present existence is a living proof of that. Now it is simple commonsense that the re-making of a thing should be relatively easier for the one who trade it for the first time .
