Standing for long periods at the mubaarak grave of Rasulullah (sallallahu alaihi wasallam)

Q: In Madinah, when standing to give salam to the Nabi ﷺ at his blessed grave, the guards usually tell you to move away after a short while. Therefore you are not able to convey salams on behalf of all people who have asked you to do so. What some people do is that they despite being told off by the guards secretly stay longer until the guards physically push them away. Is it permissible to do so, given that you are certain that you do not cause harm and do not disrupt the flow of people by staying longer? Or is it necessary to immediately obey the command of the guards to move?

Husband sending the wife government divorce notice form

Q: My husband sent ‘divorce notice form’ according to Bangladeshi Govt divorce form but his intention was to frighten and correct me . In that form he had to give right mark to ‘talaq e bain’ as there is no option there. Within one month a family meeting is occurred and we lived again as husband-wife. As Bangladeshi divorce rule, if husband take wife before 90 days, they can live as spouse.Now the question is according to Sharii, is it valid to live? If it is not valid, what should we do?

Cancelling accommodation

Q: I currently live in a hostel. I talked to another hostel owner to book a room. He kept a room for me for over 4 days and he denied other people who wanted that room. Now in the morning, the current hostel warden showed me another room with fewer charges and I decided to stay in the current hostel and not to shift. Now, if I stay, did I go against my word (wada khilafi)? I am feeling extremely guilty and I am starting to worry about my beliefs because of the backing out. Can I just say sorry and give some fine?
