a.What does “seven earths” as implied in verse 12 surah at-Talaq actually mean?
b.Why does the Quran use only a singular noun(al-ardhu) when describing the
earth(or seven earths) in this case whereas when describing seven heavens a
plural noun (as-samawat) is used?
c.Is the word as-samawat introduced by the revelation of the Quran i.e. it was
not known to be used before(maybe the Arabs only used the word as-sama’ before
the Quran was revealed)?
