Regarding the verse 71:16 : > وَجَعَلَ ٱلْقَمَرَ فِيهِنَّ نُورًا وَجَعَلَ ٱلشَّمْسَ سِرَاجًا > > And made the moon therein a [reflected] light and made the sun a > burning lamp I saw an Arab atheist claiming that the meaning of the Arabic word nur is not "reflected light"; its meaning is just "light". If its meaning is " reflected light" there is no problem, but if its meaning renders " light" there is a problem because then the above verse will be considered a scientific error. Could you please provide the proper meaning of nur according to authentic references?

We have been told about seven heavens in the Quran. Quran mentions it in 71:15 > Do you not consider how Allah has created seven heavens in layers. Also the Prophet (PBUH) went through all these heavens one by one when he was ascended to the skies. He was accompanied by Angel Gabriel in his journey and even Gabriel had to leave him alone on his last part of journey because Jabiel was not allowed to go above certain heaven (sky). **My question is, does Heaven in Quran mean Sky? What does it refer too? How can I visualize seven heavens? Can I take that as scientific statement?**
