My husband graduated from the Darze nizami system and alhamdulilah he did benefit from it, However found it hard to adapt when it came to the Arab system because a lot more memorzition was required.
At the time Deoband had good connections with Saudi Universities and a fact was that after 8 years the Darz e Nizami system had failed to produce fluent Arabic speakers. Many of the graduates understand core text but are not amazing at Arabic which the least one should be after 9 years of Arabic education.
then we have our muftis that after their ifta course go and study Arabic language in Egypt , subhanalah i have seen thousands in my 5 years in Egypt from Darul uloom azadville .
Darze nimazi needs to remove urdu all together for it be a better system and it would improve the course by miles and make it accessible to masses.
as for Al-Azhar its simply what you make of it i have seen sister come out having memorzed 4 qirat of the quran etc and some come out knowing very little.
I am personally for the African system of Sudan, Morroco,Mauritinia,Somalia and the whole of North and West Africa . where a student memorzes the mutun and the quran and the Arabic sciences.
Understanding and memorization and i belief that the above is better suited for that.
