Surah As-Saffat — Ayah 65 (37:65)
طَلۡعُهَا كَأَنَّهُۥ رُءُوسُ ٱلشَّيَٰطِينِ ٦٥
English translation (Saheeh International)
Its emerging fruit as if it was heads of the devils.
Brief commentary
The fruits that come out of it are ugly in appearance, like the heads of satans. The ugliness in appearance is a sign of ugliness in nature, which means they revolting in taste.
