Is it permissible to write a novel that portrays an individual from Gog and Magog emerging from a breach for one day, while taking into account the noble Prophetic Hadith regarding their barrier, and whose events are fictional, aiming to remind of the Hereafter and refute atheistic doubts?

Facing atheism and warning against the terrors of the Hereafter with stories free from legal prohibitions is permissible, even if they are not realistic. However, the depiction of an individual from Gog and Magog emerging in stories is not permissible, because it is not allowed to overstep the bounds of the unseen. Scriptural texts indicate that they will not be able to emerge except at the appointed time when Allah permits it, and they will not be able to breach the barrier before then. This is explained by the hadith which mentions that they dig daily but do not see the rays of the sun, and it is supported by the noble verse: {So they could not ascend over it, nor could they pierce it. He said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and the promise of my Lord is true."} The hadith that suggests the emergence of one of them is objectionable; it might be that Abu Hurayrah received it from Ka'b al-Ahbar and it was not attributed to the Prophet, peace and blessings be upon him. Therefore, the element of an individual from Gog and Magog emerging should be avoided in narrative stories.
