Surat Al Baqarah (25-26)

{ وَبَشِّرِ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ أَنَّ لَهُمْ جَنَّاتٍ تَجْرِي مِنْ تَحْتِهَا الأنْهَارُ كُلَّمَا رُزِقُوا مِنْهَا مِنْ ثَمَرَةٍ رِزْقًا قَالُوا هَذَا الَّذِي رُزِقْنَا مِنْ قَبْلُ وأُتُوا بِهِ مُتَشَابِهًا وَلَهُمْ فِيهَا أَزْوَاجٌ مُطَهَّرَةٌ وَهُمْ فِيهَا خَالِدُونَ } [البقرة:  25]

25– As for the believers, who believe in Allah and in your prophethood (O Muhammad), and in the Book which was revealed to you; and accompanied that with good deeds along with integrity and loyalty, give them the good news that they shall have wonderful gardens underneath are fresh water running to bring about energy and pleasures for them.
If they are given from the fruits of Paradise, they shall be cheered and will say: It looks like the fruit we used to eat in the world and they became happy with it. Human nature loves familiar things and averts from the unfamiliar.
So, Allah brings forth for them fruit similar to that of the world in color and appearance, but they differ in taste and size.
They will have, in Paradise, wives with bodies purified from dirt and filth.
And to ensure their happiness in that bliss, they shall live in Paradise forever.

{  إِنَّ اللَّهَ لاَ يَسْتَحْيِي أَنْ يَضْرِبَ مَثَلاً مَا بَعُوضَةً فَمَا فَوْقَهَا فَأَمَا الَّذِينَ آمَنُوا فَيَعْلَمُونَ أَنَّهُ الْحَقُّ مِنْ رَبِّهِمْ وَأَمَا الَّذِينَ كَفَرُوا فَيَقُولُونَ مَاذَا أَرَادَ اللَّهُ بِهَذَا مَثَلاً يُضِلُّ بِهِ كَثِيرًا وَيَهْدِي بِهِ كَثِيرًا وَمَا يُضِلُّ بِهِ إِلاَّ الْفَاسِقِينَ  } [البقرة: 26]

26- Allah is not shy to set forth a parable of anything, no matter how small it is, such as a mosquito or something bigger because everything Allah has created has a wisdom behind its creation.

Those who believe know that giving an example with a mosquito is true, so they have to believe in the wisdom of creation. As for the disbelievers, giving these examples increase their mischief. They will say: What is the worth of a mosquito and how much it weighs when it is compared to the world?

Mosquitoes are incredible creatures; although they are so small, mosquitoes have two big eyes composed of thousands of compound lenses. Their legs have five main joints, with a pair of claws, strong muscles stick to their chest walls, and a pin for keeping balance in their wings. The wings move near to one thousand times per second. They have systems that prevent coagulation. Mosquitoes may absorb blood that equals one and a half of their weight! They have more than three thousand species, and transmit the worst diseases. They cause millions of people to die and they spread all over the world.
