My friend Abu Zakariya of ManyProphetsOneMessage has just released this high-quality video, based partly on research I have gathered here on this blog—though I have learned several new things from it myself. I highly recommend checking it out, along with his other videos and resources.
Note: There is one inaccuracy that should be pointed out, which is that the Qur’anic hāmān and the Egyptian ḥm-‘mn do not phonetically correspond, since the former has /h/ (Arabic ه) and the latter has /ḥ/ (equivalent to Arabic ح). They therefore cannot be related.
