ل ھ مl-h-m
— The bare triliteral verb does not occur in the Quran; the original sense is that of swallowing at a single gulp (لَهِمَ الشَّيْءَlahima ash-shayʾa = he swallowed it in one go).
Form IV (ifʿāl) اَلْهَمَ يُلْهِمُ اِلْهَامًاal-hama yulhimu ilhāman: to put something into the heart, to inspire; ilhām received this name because the heart accepts it all at once. Only once in the Quran: ﴿فَاَلْهَمَهَا فُجُوْرَهَا وَتَقْوٰىهَا﴾ (Ash-Shams 91:8) — i.e. He placed in the soul the recognition of both wickedness and piety.
