Jalal al-Din al-Rumi has serval problems with regard to his creed. Some of his poems do not have a problem but others have. It is recommended not to indulge in reading those poems if you are not critical or aware of his doctrines and major leanings in aqeedah.

For the rest of stories, there is no problem as long as they do not include any thing prohibited or cause a person not to read the Quran or offer prayer regularly on time.

Allah Almighty knows best.
