I have a question about secret Nikāh. Is there any room for getting married secretly when circumstances are not favourable and when things get better, the couple in question may arrange a public ceremony and get married with the consent of all the relatives without letting them know about the first Nikāh.
A secret Nikāh is a serious violation of the very meaning which is implied in the word Nikāh. Proper announcement of marital agreement is necessary for the benefit of both parties.
The situation described by you seems an outrageous form of conspiracy. In case of unreasonable denial by the parents and relatives, one may have recourse to the court of Law but no couple has a right to get married secretly since it endangers the sanctity of the family institution.
