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?

Secret nikaah

Q: I was secretly married to my husband since 2009. Till then I meet him at his home, where his mother also stays but she doesn't have any idea. We enter his home secretly. Sometimes his brother helps us but as it is so many years his mother knows (we believe) I go to their place secretly but doesn't say anything. Is it right for me to continue this act? I am ashamed of it but he is my husband and I can't say no to him. He told me he would marry me soon, may be this year. I need your advice.
