What is the ruling on the words of a children's song that say: "Nun, nun, a pen from the inspiration of the Quran, Nun, nun, it writes for me rhyming poetry, poetry pulsating with faith"? And does the poetry here refer to the Quran or to the pen?

The verse "(Nūn) By the pen and what they inscribe" (Surat Al-Qalam) speaks of Allah swearing by the pen and what is inscribed with it, affirming that the Prophet is not mad, that he will receive a great reward, and that he possesses a tremendous character. There is disagreement regarding the interpretation of "Nūn" – whether it is a letter of the alphabet, an inkwell, or a whale beneath the earth. Similarly, there is disagreement about "the pen" – whether it refers to pens in general or specifically to the first pen created. As for the phrase "Nūn, a pen from the revelation of the Quran" in a song, it is incorrect and invalid, because "Nūn" is not the pen, and the Quran is not poetry. Caution must be exercised regarding such songs.
