What is the ruling on writing symbolic fictional stories that include superheroes who control elements, and represent a struggle between good and evil, supporting Islam and Muslims, while avoiding mentioning the name of Allah and refraining from inventing religions?

There is no harm in fictional and hypothetical stories, provided they are free from bad morals and address beneficial social issues. Litterateurs and early scholars have used this style, such as Al-Hariri in his Maqamat (assemblies), and poets in their poems which often began with imaginative introductions, and neither the Prophet (peace be upon him) nor his Companions rejected them. Furthermore, imaginative metaphors and similes were abundant in poetry and were not condemned. Permission was given to speak about the Children of Israel: "Narrate from the Children of Israel, and there is no harm," and it is well-known what their stories contain of imaginary elements. Similarly, Kalila wa Dimna by Ibn al-Muqaffa', which is a fictional book narrated by animals, was accepted by scholars.
