What are the worlds? I know heaven and the earth are different worlds, but how many are there? What are all the worlds actually? What does Islam say?
The word Al-Alamin (the worlds/universes) literally translates to "everything that exists other than Allah." It is not limited to physical planets. It includes:
Islam does not give a specific mathematical number for how many worlds exist. Some classical scholars used large numbers (like 80,000) simply as a figure of speech to mean "countless." Ultimately, the Quran teaches that the true scale, diversity, and number of these worlds are known only to God.
What does this mean? Can we read Alif as I, Lam as L, and Mim as M to make the word "ILM" (which means knowledge)? Is Allah saying everything coming next is knowledge?
While connecting it to the word "Ilm" (knowledge) is a beautiful thought, linguistically and theologically, it means something else:
If Verse 2 says this book is a guide for the mindful, how can they already be praying and donating? Is the Quran essentially saying it's a guide to *teach* the mindful to pray and give, rather than requiring them to already do it?
Yes, exactly. It is not a prerequisite; it is the resulting destination.
