Lady who was ready to accept Islam passing away

Q: I had gotten married to a Christian woman in order to avoid zina, with her having an interest in Islam at that stage. After a few months, she was prepared to become Muslim, but due to bad habits of mine, she didn't want to take the shahada as she wanted me to be of sober habit and mind in order to guide her through the transition. In the past month and a half she constantly reprimanded me with regards to my habit, saying she is ready for the shahada, and eventually she told me she will take the shahada regardless of my amendment of my ways. She even went to madrasah and began reading Islamic kitaabs. Two weeks ago she passed away in a car accident. Due to us living in separate towns, I do not know if she took the shahada or not. Is it permissible for me to send esaale thawaab for the deceased? In the case that she never took shahada, I am in great fear of Allah's punishment. It was my weakness that caused delay in the issue. What would Mufti Saheb advise so that Allah may forgive me and not take me to task through the deceased taking me to task?

A: Apparently it seems that she had taken the shahaadah because she had resolved of taking shahaadah irrespective of your ways. You should make du`aa for her. May Allah Ta`ala give her the good of the hereafter.

And Allah Ta'ala (الله تعالى) knows best.
