نَحْنُ خَلَقْنَاهُمْ وَشَدَدْنَا أَسْرَهُمْ
...
It is We Who created them, and We have made them of strong build.
Ibn `Abbas, Mujahid and others have said,
"This means their creation."
...
وَإِذَا شِيْنَا بَدَّلْنَا أَمْثَالَهُمْ تَبْدِيلًإ
And when We will, We can replace them with others like them with a complete replacement.
meaning, `when We wish, We will resurrect them on the Day of Judgement and change them, repeating their creation in a new form.'
Here the beginning of their creation is a proof for the repetition of their creation.
Ibn Zayd and Ibn Jarir both said,
وَإِذَا شِيْنَا بَدَّلْنَا أَمْثَالَهُمْ تَبْدِيلًإ
(And when We will, We can replace them with others like them with a complete replacement.)
"This means, if We wish We can bring another group of people besides them (in their place)."
This is like Allah's statement,
إِن يَشَأْ يُذْهِبْكُمْ أَيُّهَا النَّاسُ وَيَأْتِ بِـاخَرِينَ وَكَانَ اللَّهُ عَلَى ذلِكَ قَدِيراً
If He wills, He can take you away, O people, and bring others. And Allah is capable over that. (4:133)
This is also like His statement,
إِن يَشَأْ يُذْهِبْكُـمْ وَيَأْتِ بِخَلْقٍ جَدِيدٍ وَمَا ذَلِكَ عَلَى اللَّهِ بِعَزِيزٍ
If He wills, He can remove you and bring a new creation! And for Allah that is not hard or difficult. (14:19-20)
The Qur'an is a Reminder, and Guidance comes from the Help of Allah
Allah then says,
