Advice for children to learn

Q: Please help me with any dua or wazifa to make the brain strong for reading, understanding and implementing.

1. My 4 year old kid is not learning anything at all and is very stubborn. I believe his mind is not towards studying. Please suggest a wazifa to sharpen his brain to study well.

2. For myself, I am 36 years old and I want an upgrade in my career and want to learn some courses. Please suggest a wazifa so that I can also concentrate on my studies as my brain is also not sharp in studies.

Watching a documentary on Egyptian mummies

Q: A few days ago I was watching a documentary on YouTube about the king of Egypt named Tutankhamun. In this video, the youtuber said that after the death of this king, whoever passes by the mummy of this king, they died after few days. After this people started calling this mummy cursed.

Now some people commented and were asking that they are also in danger or not after they saw this video.

Also, in the video they showed the real pics of this mummy. I know that there is no concept of superstition in Islam. My question is that is this coincidence that people died after passing this mummy ? Not all the people died but some. People feel frightened because they saw real muumuy pics. 

Sun rising from the west before Qiyaamah

Q: My question is about sunset and sunrise. We learnt that one of the signs of Qiyaamat is that the sun will rise from the west. We know that the sun rises in the east and sets in the west, but scientists say that it the earth is rotating around the sun. So the sun is not moving because the Earth is rotating on an axis around it.

In the Quraan or Hadith it is written that the sun rises in the east and sets in the west but before Qiyamat, it will rise in the west and set in the east. So this point is opposite of the reality that we know where the sun is actually not moving and is at the same place but the earth is moving. It seems that the Quraan and Hadith is contracting with the reality? How is it possible?
