I have had an operation to remove a tumor from my lower abdomen. After that, I lost my ability to have children. A year later, I had another surgery and, thanks to Allah, it was successful and doctors told me that I can have children. I proposed to two women and told them about what happened to me, but their parents refused fearing that I could still be sterile. Now, I`m about to propose to a new woman. Should I tell her about that surgery to avoid being turned down or it isn`t permissible to do so?
