According to the well-known hadith aquiring knowlegde is obligatory (fard) for us muslims. Now I'd like to know insha Allah which and how much knowledge is individually fard?
If l learn this book by heart, will I already have fulfilled the obligation or do I need to know more?
If the above-mentioned book doesn't suffice, could you maybe point out a book covering (only!) the absolutely obligatory knowledge in a precise and easy-to-learn style?
Barak Allah fikum
