We will answer by quoting a number of aayaat (verses) from the Book of Allaah (the Qur’aan – the scripture of Islam), then you can think to yourself about the matter and if the truth becomes clear to you, you will have no choice but to follow it. Allaah says (interpretation of the meaning): “We created you, then why do you believe not?
Then tell Me (about) the human semen that you emit.
Is it you who create it (i.e., make this semen into a perfect human being), or are We the Creator?
We have decreed death unto you all, and We are not unable,
To transfigure you and create you in (forms) that you know not.
And indeed, you have already known the first form of creation (i.e., the creation of Adam). Why then do you not remember or take heed?
Tell Me! The seed that you sow in the ground.
Is it you that make it grow, or are We the Grower?
Were it Our Will, We could crumble it to dry pieces, and you would be regretful (or left in wonderment),
(Saying), ‘We are indeed Mughramoon (i.e., ruined, or lost the money without any profit, or punished by the loss of all that we spent for cultivation, etc.)!
‘Nay, but we are deprived!’
Tell Me! The water that you drink,
Is it you who cause it from the rainclouds to come down, or are We the Causer of it to come down?
If We willed, We verily could make it salt (and undrinkable). Why then do you not give thanks (to Allaah)?
Tell Me! The fire which you kindle,
Is it you who made the tree thereof to grow, or are We the Grower?
We have made it a Reminder (for the Hell-fire, in the Hereafter); and an article of use for the travellers (and all others, in this world).
The glorify with praises the Name of your Lord, the Most Great.
So I swear by mawaaqi’ (setting to the mansions, etc.) of the stars (they traverse),
And verily, that is indeed a great oath, if you but knew,
That (this) is indeed an honourable recital (the Noble Qur’aan).” [Quran 56:57-77]
Were they created by nothing, or were they themselves the creators?
Or did they create the heavens and the earth? Nay, but they have no firm Belief. Or are with them the treasures of your Lord? Or are they the tyrants with the authority to do as they like?” [Quran 52:35-37]
“Verily, the creation of the heavens and the earth, and in the alternation of night and day, and the ships which sail through the sea with that which is of use to mankind, and the water (rain) which Allaah sends down from the sky and makes the earth alive therewith after its death, and the moving (living) creatures of all kinds that He has scattered therein, and in the veering of winds and clouds which are held between the sky and the earth, are indeed aayaat (proofs, evidences, signs) for people of understanding.” [Quran 2:164]
“It is He Who sends down water (rain) from the sky, and with it We bring forth vegetation of all kinds, and out of it We bring forth green stalks, from which We bring forth thick clustered grain. And out of the date-palm and its spathe come forth clusters of dates hanging low and near, and gardens of grapes, olives and pomegranates, each similar (in kind) yet different (in variety and taste). Look at their fruits when they begin to bear, and the ripeness thereof. Verily! In these things there are signs for people who believe.” [Quran 6:99]
“And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain), till when they have carried a heavy-laden cloud, We drive it to a land that is dead, then We cause water (rain) to descend thereon. Then We produce every kind of fruit therewith. Similarly, We shall raise up the dead, so that you may remember or take heed.” [Quran 7:57]
“Is not He (better than your gods) Who created the heavens and the earth, and sends down for you water (rain) from the sky, whereby We cause to grow wonderful gardens full of beauty and delight? It is not in your ability to cause the growth of their trees. Is there any god with Allaah? Nay, but they are a people who ascribe equals (to Him)!” [Quran 27:60]
“He has created the heavens and the earth without any pillars that you see, and has set on the earth firm mountains, lest it should shake with you. And He has scattered therein moving (living) creatures of all kinds. And We send down water (rain) from the sky, and We cause (plants) of every goodly kind to grow therein.” [Quran 31:10]
And the two seas (kinds of water) are not alike, this fresh, sweet and pleasant to drink, and that saltish and bitter. And from them both you eat fresh tender meat (fish), and derive the ornaments that you wear. And you see the ships cleaving (the sea-water as they sail through it), that you may seek of His Bounty, and that you may give thanks.” [Quran 35:12]
And it is He Who has let free the two seas (kinds of water), one palatable and sweet, and the other salt and bitter, and He has set a barrier and a complete partition between them.” [Quran 25:53]
