How can I choose the right wife after a first marriage experience that was not built on religious foundations? And is a girl who does not currently wear the hijab but has no objection to wearing it suitable? What is the correct role of Istikhara prayer and how can its results be understood in this choice?

It is advisable to avoid marriages based on online introductions, due to their high failure rate caused by deception. It is important to perform Istikhara (prayer for guidance) when choosing a wife, because Allah knows best what is in the souls. As for the girl mentioned, her negligence regarding the hijab is a serious matter, as it is an obligation. It is not advisable to propose to her unless she truly commits to it and her sincerity is confirmed. Often, the desire for marriage can be a motive to express a desire for hijab without actually committing to it, which could negatively affect the husband and his religious practice.
