All praise due to Allah, if you are reading this on Tuesday/Wednesday night (August 4/5) then I strongly suggest that you turn off your monitor, your room lights (might as well turn of all the house lights and save electricity) and then go outside and watch the light show from the sun. You will see it in the northern part of the sky.
It is beautiful, Subhan’Allah and well worth your time. It might at first look like lightening, but then realize that there is no storm around you, nor any sound. It just a light show worth seeing and it is much more beautiful than any firework display I have ever seen.
If you are watching it or saw it, then kudos to you.
