Signs of Allah's Existence
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 الْجِبَالِ جُدَدٌ بِيضٌ وَحُمْرٌ مُّخْتَلِفٌ أَلْوَنُهَا وَغَرَابِيبُ سُودٌوَمِنَ النَّاسِ وَالدَّوَآبِّ وَالاٌّنْعَـمِ مُخْتَلِفٌ أَلْوَنُهُ كَذَلِكَ إِنَّمَا يَخْشَى اللَّهَ مِنْ عِبَادِهِ الْعُلَمَاءُ]
(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 كُنتُمْ فِى رَيْبٍ مِّمَّا نَزَّلْنَا عَلَى عَبْدِنَا فَأْتُواْ بِسُورَةٍ مِّن مِّثْلِهِ وَادْعُواْ شُهَدَآءَكُم مِّن دُونِ اللَّهِ إِن كُنتُمْ صَـدِقِينَ - فَإِن لَّمْ تَفْعَلُواْ وَلَن تَفْعَلُواْ فَاتَّقُواْ النَّارَ الَّتِى وَقُودُهَا النَّاسُ وَالْحِجَارَةُ أُعِدَّتْ لِلْكَـفِرِينَ ]
(23. And if you (Arab pagans, Jews, and Christians) are in doubt concerning that which We have sent down (i.e. the Qur'an) to Our servant (Muhammad ), then produce a Surah (chapter) of the like thereof and call your witnesses (supporters and helpers) besides Allah, if you are truthful). (24. But if you do it not, and you can never do it, then fear the Fire (Hell) whose fuel is men and stones, prepared for the disbelievers.)
