Qur’an and Knowledge 6item In the present age Russian and American scientists have succeeded in conquering to a certain extent some of the planets. In the Holy Quran is there any reference to this or not? And will they get more successes regarding them or not? Astronomers believe that the shape of the Earth is spherical and it revolves around its axis; is it confirmed by science or still undecided? And if the Earth really revolves what are its scientific and perceptible signs? What is the reason that the Polestar, by means of which direction of Qibla is ascertained, always shows up at the same location? Other than this, is there any matter available in the Holy Quran and Islamic traditions that supports this? Is there evidence in the Holy Quran and traditions regarding the Earth being spherical? Surah 21:30 does it in any way refers to the theory of Big Bang? A tradition attributed to the holy Imam al Baqir seems contrary. Commentary of Quran by Mir Ahmed Ali with special notes from Agha Pooya Yazdi page 1008 to 1009. Is there any relationship between the theory of Big bang and Surah al-Anbiya verse 30. Meanwhile in the English commentary of the holy Quran by Mir Ahmed Ali with some special notes from Agha Pooya Yazdi page 1008 to 1009, a hadith is attributed to holy Imam Baqir (a.s) which seems contrary to d Big Bang. Please elaborate. A non-Muslim friend asked me a question about the Quran. He said, "How can it be something Holy, if there is such a bad scientific mistake...the sort of mistake a man would make if he were to try to make something that wasn't really inspired by God?" He gave me an example of Sura Al-Kahf verse 86. "Until, when he reached the setting sun, he found it set in a spring of murky water." What is your interpretation of this verse?
