The seven heavens refer to the seven heavenly bodies in ancient religions.
Back in those days, instead of planets, we had the "seven heavenly bodies":
Moon > Mercury > Venus > Sun > Mars > Jupiter > Saturn
When Muslims circumambulate the black cube seven times, they are in fact paying tribute to these seven heavenly bodies. Our days are named after some of these heavenly bodies:
Saturday - Saturn
Sunday - Sun
Monday - Moon
Wednesday - Venus
Thursday and Friday are named after the ancient deities "Thor" and "Frida", I don't remember where we get Tuesday from. However, this explains why Christians worship on Sunday, or the day of the Sun, as Jesus was the "light of the world" or the "risen savior".
Once again, visit the links that I gave above. What you posted was from Greek Mythology. We don't care about it and it is not original in anyway. Besides, the days' names in Arabic are nothing about planets. They are:
1- Al-Ahad - The singular, the one, the beginning.
2- Al-Ithnayn - the Dual.
3- Al-Thulatha - The Triple.
4- Al-Arbiaa - The Quadruple.
5- Al-Khamees - the Quintuple.
6- Al-Jumuah - The Gathering, the Group. This is where Muslims pray the Jumuah Prayer in group.
It is mandatory upon all Muslims.7- Al-Sabt - Named after the Jewish Holy Sabbath that was decreed by Allah Almighty upon the Jews.
Nothing about planets here.
Your Greek Mythology is empty. It doesn't disprove Islam. And once again, the Glorious Quran's Claims about the Earth and the Atmosphere were scientifically proven to be Miraculous.
The doomed-to-Hell infidels have nothing on Islam. I challenge you to refute the article that I gave you above.
I am waiting....Take care,
