Q: I am engaged to be married. My bride to be is doing her degree from home. She wants to stay at home till completion.

Q: I am a 26 year old girl. I got a proposal last year and it's already been a year. He and his family are assuring us that once he gets a job and settles, then only will we proceed further. My parents are very worried about me. I dont want to be the reason of my parents sadness. Actually the main problem is that he is from South and I am from North. In South marriage, there willbe a grand show off and all that but currently he is jobless. My parents still agreed and are ready but he is stuck on one thing that he needs a job. We must just wait 8 more months. I just want a halal relationship. One more thing I would like to ask is that we did a register marriage in January 2017, just to avoid wrong deeds but now I am feeling that without Allah's blessing how can we be happy. So I am insisting to get marry according Islamic shariya but he says that he can't do it now and he needs time. Please suggest what to do because I am completely lost. I really dont know what to do.

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.

Q: I am getting married soon, Insha Allah. Please provide me with the step-by-step sunnah way of nikkah and what is required to make the nikaah valid. Also, what is the difference between a wali and waqeel, and who would suffice as a witness for both bride and groom?
