If Lane is correct in his explanatory note for Hudā’ [inaccurately transliterated here as Heda’a]- “It is said that it originated from the fact of a Desert Arab beating his boy and biting his fingers, whereupon he went along saying Dai!

[O My Two Hands!], and the camels went on at his cry”- one can imagine that this cultural practice comes from a dark place, far darker than Idris tapped when he sang to his camel, O Rocket of Sudan!, Your Eye Like a Seiko Watch.
