Al-Baqarah : 163:
وَإِلَـٰهُكُمْ إِلَـٰهٌ وَاحِدٌ ۖ لَّا إِلَـٰهَ إِلَّا هُوَ الرَّحْمَـٰنُ الرَّحِيمُ ﴿١٦٣﴾
And your God is one God! there is no god but He; He is the Beneficent, the Merciful.
These ayah is considered as the verse of Tawheed - the Oneness of Allah. This is to say that every creatures in world has only one God, the one and only God, Allah SWT. He is Beneficent and Merciful to all livings in the world.
This ayah is followed by another ayah that thells the proof of Allah as the one and only God.
إِنَّ فِي خَلْقِ السَّمَاوَاتِ وَالْأَرْضِ وَاخْتِلَافِ اللَّيْلِ وَالنَّهَارِ وَالْفُلْكِ الَّتِي تَجْرِي فِي الْبَحْرِ بِمَا يَنفَعُ النَّاسَ وَمَا أَنزَلَ اللَّـهُ مِنَ السَّمَاءِ مِن مَّاءٍ فَأَحْيَا بِهِ الْأَرْضَ بَعْدَ مَوْتِهَا وَبَثَّ فِيهَا مِن كُلِّ دَابَّةٍ وَتَصْرِيفِ الرِّيَاحِ وَالسَّحَابِ الْمُسَخَّرِ بَيْنَ السَّمَاءِ وَالْأَرْضِ لَآيَاتٍ لِّقَوْمٍ يَعْقِلُونَ ﴿١٦٤﴾
Most surely in the creation of the heavens and the earth and the alternation of the night and the day, and the ships that run in the sea with that which profits men, and the water that Allah sends down from the cloud, then gives life with it to the earth after its death and spreads in it all (kinds of) animals, and the changing of the winds and the clouds made subservient between the heaven and the earth, there are signs for a people who understand.
It tells of the Mighty Allah and HIS creation. Allah creates to the benefit of the mankind. Only if the mankind thinks about it.
- Allah creates the sky and the land, from where, comes the day and night which rotates in a certain nature and benefits all.
- Allah creates the ocean, from where, mankind are able to travel to unknown places all over the earth.
- Allah creates rain, which comes down from the above, from where it wet the land after a long draught, and grow plants which becomes food to many.
- Allah creates the animals roaming around the land.
- Allah creates the wind that at times bring the heavy clouds bearing water, and at times pushes the clouds away.
- Allah creates the clouds that moves from one place to another between the sky and land.
All the creations are none other for the people to think and understand that Allah is the most powerful and Merciful.
