Please translate the following from Suratil Baqarah searching any new verbs/nouns that have not yet been encountered. Please provide any additional explanation where you see necessary.


وَاللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ


New questions may arise as a result of pondering over this question. If this is so, please create a new thread.

السلامة عليكم

وَاللَّهُ - And Allah
يَعْلَمُ - knows
وَأَنتُمْ - and you
لَا تَعْلَمُونَ - (do) not know*

* I think this could be 'and you are not knowing' as in you are not seeing what is right? It's the لَا which I'm finding quite confusing to translate.

مع السلامة
