like i said i only want advice on how she can influence her husband to be more pious. you dont need to know personal details about their lives. she isnt being held at gunpoint, she agreed to the marriage herself but now she has become more religious. cultural issues prevent her from ending it because of what could very well happen. thats all i say on that issue!
now please, ONLY ADVICE ON HOW to guide him to be more pious. he is already muslims and admires the religion...i must say i feel this wasnt the right place to come ask people ask too many questions and ont give answers
Very well, very well, just take it easy with the frustration sister.
First remind her that if he doesn't start praying, the marriage is void and she is performing daily zina with a kafir. Just remind her of that.
Second, she can actually use that as an angle: that their marriage is not correct until he at least start the five prayers, so he can make that her marriage gift.
The sunnah showed us that a companion was brought to Islam that way, when Abu Talha liked Umm Sulaim Arrumaisa', a muslim woman, and asked her to marry him, she told him her dowry is for him to become muslim, which he obliged. That man went on to be a close companion of the prophet -s.a.a.w.-.
Also people like to follow example. If he sees her pious and enjoying her prayer and quran, he will be inquisitive. If she brings stuff over to him and then "ask" him about its meaning or its ruling, making him feel sought for his exquisite advice and knowledge (many men love that and women can really play them

), or she can ask him to check with the imam of the masjid (making him GO to the masjid instead of praying at home), that can lead to useful things.
Hope that helps.
