Many of the discoveries of science are by accident and not by design. The research was on something else and something was discovered which could be used for something else. 
Reading and research are part of our tradition in Islam and just because we have gone away from our tradition, we look at the Modern science and due to inferiority complex think that those doing reserach are superhuman or are inspired by Jinn etc.
Its all about oppurtunities and if we provide them to practising Muslims and back talent you will see results. In most Muslim countries, socities and culture talent is not backed...It isn't about you but who backs you.

There will be three hard years before the Dajjal (appears). During them, people will be stricken by a great famine. In the first year, Allah will command the sky to withhold a third of its rain, and the earth to withhold a third a third of its produce. In the second year, Allah will command the sky to withhold two thirds of its rain, and the earth to withhold two thirds of its produce. In the third year, Allah will command the sky to withhold all of its rain, and it will not rain a single drop of rain. He will command the earth to withhold all of its produce, and no plant will grow. All hoofed animals will perish, except that which Allah wills. [Ibn Khuzaymah]
The rain cycle is well understood. Water evaporates and then cools down in the clouds and the droplets get bigger. When it gets too heavy it drops back down to Earth.

You cannot create rainclouds or make it rain. All you can do is to make the water condense into ice particles (so they get heavy) and as they get heavier they fall back on Earth causing rain. The ingredient used is Silver Iodide and it is done in two ways:

Here is a Canon in Tibet (China) for cloud-seeding:

Here is an aeroplane for cloud-seeding:

Problems with the technology:
The technology of cloud seeding is old and one of the first tests were conducted in 1948 and termed as Schaefer-Langmuir Cloud-Seeding some problems have remained:
Dajjal:
We know that Dajjal will have access to Shaytaanic and Jinn forces so it is my speculation that it is possible for Jinns to move clouds as we know from the Qur’aan that Jinns are able to move objects:
[Solomon] said, "O assembly [of jinn], which of you will bring me her throne before they come to me in submission?" A powerful one from among the jinn said, "I will bring it to you before you rise from your place, and indeed, I am for this [task] strong and trustworthy." Said one who had knowledge from the Scripture, "I will bring it to you before your glance returns to you." And when [Solomon] saw it placed before him, he said, "This is from the favor of my Lord to test me whether I will be grateful or ungrateful. And whoever is grateful - his gratitude is only for [the benefit of] himself. And whoever is ungrateful - then indeed, my Lord is Free of need and Generous." [2&;38-40]
Money is no object.
The most ambitious project in the world is being conducted in Tibet (China) and the idea is to fire Silver iodide into the clouds which already have the moisture to make it rain in the Tibetan plateau.

Again, the most public display was during the Beijing Olympics when China fired canons in the sky to make it rain (prematurely) and ensure that the Olympics were relatively rain free.
You can seed the clouds prematurely so by the time clouds get to another location they are moisture free because the rain has already fallen.

While China is spending millions on cloud-seeding and leading ambitious projects to combat water shortages in 2020, scientists in Israel are throwing cold water on the technology and saying it is not as effective as once thought:

The 2010 Israeli study has effectively put a stop to the popularity of cloud seeding in the west even though the Wyoming Weather Modification Pilot and other studies in America have shown promise:

P.S: It is enitrely possible that the conditions for cloud-seeding are not suited in Isarel but they are in parts of Americ and China.
                
                
                
                
                
                
That is the whole point of making people understand something, when you understand something you are not easily impressed by it.
When you show card tricks to people and they don’t understand it they are mightily impressed and they think that you have some magical powers but when you understand it you are not in a shock.
Dajjal may make it rain and its impressive and awesome for people. When you actually break it down that all it is making the water freeze (so it gets heavier) and falls back down, all of a sudden it is not as impressive.
You are right that the technology being discussed is old and it is likely that newer technology will be used by Dajjal BUT when people understand how something works clearly they WILL NOT be impressed and that is the point.
Educate people on how some of these things may happen instead of shying away from the topic.

I would like to suggest that this applies to Dajjal and its army and this is a relatively easy topic to discuss
Some people are naturally bigger. However, in our times diets/drugs/techniques are widely and readily available to make you bigger. Actors generally transform in a relatively short of amount and get huge in 6-9 months with professional assistance.
For general laymen, Anabolic steroids are easily and readily available.
My point is that it is not difficult to get huge in relatively modest time scales and since Dajjal will have access to great scientific/technical research and financial resources this will not be a problem for him or his army (both men and women) to be physically huge. 
There are two aspects to strength:
Part 1 of this post deal with 1 but pioneering research into exoskeletons shows that human strength can be easily augmented and extended by using exoskeletons. The civilian products already available are cutting edge


The military research into this area is obviously classified but we already know that they are working on powered exoskeletons which will extend the strength factor even further.
Again, Dajjal will have no problems with access to cutting edge exoskeletons and associated augmented and enhanced strength, for himself or his army.

Some people are naturally fearless and brave. However, humans can be easily drugged to make them oblivious to their fears. Synthetic drugs (Monkey dust etc) are easily available to make people feel invincible and to make them jump off roofs etc.
Again, Dajjal will have no problems with access to drugs to make fear disappear, for himself or his army.
I have seen plenty of drugged up people do all sorts of things which sober people will not so this is entirely possible. The question should now ask is drugged people are not in control of their faculties so how do you drug people but also make them fully cognizant? Read on to the next section...

There is no point in being big, super strong, powerful and fearless but if you don't have the endurance and alertness to withstand the rigours of life. 
This is achieved by amphetamines. 

The use of amphetamines in US Air force is already prevalent and well known.

The Air force openly admits and justifies the use of amphetamines.

Again, Dajjal will have no problems with access to drugs to enhance alertness and endurance, for himself or his army, this is easy to understand.

This cannot be undone and I am sure it will be greatly appreciated.
