dars-e-nizaami

Q:

1- Some of our own Deobandi ulama have one objection on the Darse Nizami system that Darse-Nizami focuses of Fiqh and comparitive Fiqh even when teaching the Hadith books, hence a Darse-Nizami graduate does not have much expertise in Hadith and Usool-e-Hadith and related Hadith sciences. What is the answer to such people?

2 - How can a Darse Nizami student ensure that he becomes an expert and master of Hadith sciences(such as Asma ur Rijaal etc) and Usool e Hadith?

3 - Who were some Hadith and Hadith sciences experts among Ulama-e-Deoband? Can you please mention a few names.

4- If anyone from among Ulama e Deoband  was particularly expert in the science of Asma ur Rijal please mention it.

5- Maulana Habib ur Rahman Azami (died 1992 ) was considered  a master of Hadith and its sciences , in addition to being an expert in Fiqh and a knowledgable Mufti as well. Is this correct?
