29:20
قُلْ سِيرُوا۟ فِى ٱلْأَرْضِ فَٱنظُرُوا۟ كَيْفَ بَدَأَ ٱلْخَلْقَ ۚ ثُمَّ ٱللَّهُ يُنشِئُ ٱلنَّشْأَةَ ٱلْـَٔاخِرَةَ ۚ إِنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ
Say, [O Muhammad], "Travel through the land and observe how He began creation. Then Allah will produce the final creation. Indeed Allah, over all things, is competent."

وَإِن تُكَذِّبُوا۟ فَقَدْ كَذَّبَ أُمَمٌ مِّن قَبْلِكُمْ ۖ وَمَا عَلَى ٱلرَّسُولِ إِلَّا ٱلْبَلَـٰغُ ٱلْمُبِينُ
And if you [people] deny [the message] - already nations before you have denied. And there is not upon the Messenger except [the duty of] clear notification.
أَوَلَمْ يَرَوْا۟ كَيْفَ يُبْدِئُ ٱللَّهُ ٱلْخَلْقَ ثُمَّ يُعِيدُهُۥٓ ۚ إِنَّ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرٌ
Have they not considered how Allah begins creation and then repeats it? Indeed that, for Allah, is easy.
يُعَذِّبُ مَن يَشَآءُ وَيَرْحَمُ مَن يَشَآءُ ۖ وَإِلَيْهِ تُقْلَبُونَ
He punishes whom He wills and has mercy upon whom He wills, and to Him you will be returned.
وَمَآ أَنتُم بِمُعْجِزِينَ فِى ٱلْأَرْضِ وَلَا فِى ٱلسَّمَآءِ ۖ وَمَا لَكُم مِّن دُونِ ٱللَّهِ مِن وَلِىٍّ وَلَا نَصِيرٍ
And you will not cause failure [to Allah] upon the earth or in the heaven. And you have not other than Allah any protector or any helper.
