Learn the Arabic of the Qur'an and Hadiths through the stories of the Prophets, inshaAllah. Not vocabulary and grammar you'll never use.
The stories start almost entirely in English, with only a few Arabic words. Chapter by chapter the Arabic increases, until inshaAllah you're starting to understand parts of the Qur'an you recite and hadith you read.
No memorising long lists of words you'll never come across in the Qur'an. No grinding through grammar tables. Just the words and grammar you'll actually use.
Arabic is too vast to master from one book. But inshaAllah, this one gives you the foundation to build on.
A foundation built for the one reason you wanted Arabic in the first place.
