Several scholars of Tafsir, like Ar-Razi and others, used these Ayat as an argument for the existence of the Creator, and it is a most worthy method of argument. Indeed, whoever ponders over the things that exist, the higher and lower creatures, their various shapes, colors, behavior, benefits and ecological roles, then he will realize the ability, wisdom, knowledge, perfection and majesty of their Creator. Once a bedouin was asked about the evidence to Allah's existence, he responded, "All praise is due to Allah! The camel's dung testifies to the existence of the camel, and the track testifies to the fact that someone was walking. A sky that holds the giant stars, a land that has fairways and a sea that has waves, does not all of this testify that the Most Kind, Most Knowledgeable exists''
Hence, whoever gazes at the sky in its immensity, its expanse, and the various kinds of planets in it, some of which appear stationary in the sky - whoever gazes at the seas that surround the land from all sides, and the mountains that were placed on the earth to stabilize it, so that whoever lives on land, whatever their shape and color, are able to live and thrive - whoever reads Allah's statement,
﴿ وَمِنَ ٱلۡجِبَالِ جُدَدُۢ بِيضٌ۬ وَحُمۡرٌ۬ مُّخۡتَلِفٌ أَلۡوَٲنُہَا وَغَرَابِيبُ سُودٌ۬ • وَمِنَ ٱلنَّاسِ وَٱلدَّوَآبِّ وَٱلۡأَنۡعَـٰمِ مُخۡتَلِفٌ أَلۡوَٲنُهُ ۥ كَذَٲلِكَۗ إِنَّمَا يَخۡشَى ٱللَّهَ مِنۡ عِبَادِهِ ٱلۡعُلَمَـٰٓؤُاْۗ ﴾
(And among the mountains are streaks white and red, of varying colours and (others) very black. And likewise, men and Ad-Dawabb (moving (living) creatures, beasts) and cattle are of various colours. It is only those who have knowledge among His servants that fear Allah) (35: 27-28).
Whoever thinks about the running rivers that travel from area to area bringing benefit, whoever ponders over what Allah has created on earth; various animals and plants of different tastes, scents, shapes and colors that are a result of unity between land and water, whoever thinks about all of this then he will realize that these facts testify to the existence of the Creator, His perfect ability, wisdom, mercy, kindness, generosity and His overall compassion for His creation. There is no deity worthy of worship except Allah, nor is there a Lord besides Him, upon Him we rely and to Him we turn in repentance. There are numerous Ayat in the Qur'an on this subject.
﴿ وَإِن ڪُنتُمۡ فِى رَيۡبٍ۬ مِّمَّا نَزَّلۡنَا عَلَىٰ عَبۡدِنَا فَأۡتُواْ بِسُورَةٍ۬ مِّن مِّثۡلِهِۦ وَٱدۡعُواْ شُهَدَآءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَـٰدِقِينَ • فَإِن لَّمۡ تَفۡعَلُواْ وَلَن تَفۡعَلُواْ فَٱتَّقُواْ ٱلنَّارَ ٱلَّتِى وَقُودُهَا ٱلنَّاسُ وَٱلۡحِجَارَةُۖ أُعِدَّتۡ لِلۡكَـٰفِرِينَ ﴾
Many of the Imams of the Sunnah used this Ayah to prove that the Fire exists now. This is because Allah said,
﴿ أُعِدَّتۡ ﴾
(prepared) meaning, prepared and kept. There are many Hadiths on this subject. For instance, the Prophet said,
« تَحَاجَّتِ الْجَنَّةُ وَالنَّار »
(Paradise and the Fire had an argument…)
Also, the Prophet said,
« اسْتَأْذَنَتِ النَّارُ رَبَّهَا فَقَالَتْ: رَبِّ أَكَلَ بَعضِي بَعْضًا فَأذِنَ لَهَا بِنَفَسَيْنِ: نَفَسٍ فِي الشِّتَاءِ وَنَفَسٍ فِي الصَّيْف »
(The Fire sought the permission of her Lord. She said, 'O my Lord! Some parts of me consumed the other parts.' And Allah allowed her two periods to exhale, one in winter and one in summer.)
Also, there is a Hadith recorded from Ibn Mas`ud that the Companions heard the sound of a falling object. When they asked about it, the Messenger of Allah said,
« هَذَا حَجَرٌ أُلْقِيَ بِهِ مِنْ شَفِيرِ جَهَنَّمَ مُنْذُ سَبْعِينَ سَنَةً، الْآنَ وَصَلَ إِلى قَعْرِهَا »
(This is a stone that was thrown from the top of Jahannam seventy years ago, but only now reached its bottom.) This Hadith is in Sahih Muslim.
There are many Hadiths that are Mutawatir (narrated by many different chains of narrations) on this subject, such as the Hadiths about the eclipse prayer, the night of Isra' etc.
Allah's statements,
﴿ فَأۡتُواْ بِسُورَةٍ۬ مِّن مِّثۡلِهِۦ ﴾
(Then produce a Surah (chapter) of the like thereof) (2:23), and,
﴿ بِسُورَةٍ۬ مِّثۡلِهِۦ ﴾
(A Surah (chapter) like it) (10:38) this includes the short and long Surahs of the Qur'an. Therefore, the challenge to creation stands with regards to both the long and short Surahs, and there is no disagreement that I know of on this fact between the scholars of old and new. Before he became Muslim, `Amr bin Al-`As met Musaylimah the Liar who asked him, "What has recently been revealed to your fellow (meaning Muhammad) in Makkah'' `Amr said, "A short, yet eloquent Surah.'' He asked, "What is it'' He said,
﴿ وَٱلۡعَصۡرِ • إِنَّ ٱلۡإِنسَـٰنَ لَفِى خُسۡرٍ ﴾
(By Al-`Asr (the time). Verily, man is in loss,) (103:1-2)
Musaylimah thought for a while and said, "A similar Surah was also revealed to me.'' `Amr asked, "What is it'' He said, "O Wabr, O Wabr (i.e. a wild cat), you are but two ears and a chest, and the rest of you is unworthy and thin.'' `Amr said, "By Allah! You know that I know that you are lying.''
﴿ وَبَشِّرِ ٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّـٰلِحَـٰتِ أَنَّ لَهُمۡ جَنَّـٰتٍ۬ تَجۡرِى مِن تَحۡتِهَا ٱلۡأَنۡهَـٰرُۖ ڪُلَّمَا رُزِقُواْ مِنۡہَا مِن ثَمَرَةٍ۬ رِّزۡقً۬اۙ قَالُواْ هَـٰذَا ٱلَّذِى رُزِقۡنَا مِن قَبۡلُۖ وَأُتُواْ بِهِۦ مُتَشَـٰبِهً۬اۖ وَلَهُمۡ فِيهَآ أَزۡوَٲجٌ۬ مُّطَهَّرَةٌ۬ۖ وَهُمۡ فِيهَا خَـٰلِدُونَ ﴾
