* How does mithlahunna mean " similuar to them" ?
* Where is the preposition "to" coming from ?
* I would like to know how a possesive case became a preposition ?
* You said that verse says 7 earths would you mind explaining also what is the subject and what is the predicate in
Allahu allathee khalaqa sabAAa samawatin wamina al-ardi mithlahunna..
for you to claim that verse expresses 7 earths ?
Care to answer these questions ? And no you do not understand Classical Arabic when you dont even understand arabic grammar.
