Nod

a nod to the nabir is better than wink to the wabsanti

In part, a reference to the phrase "a nod's as good as a wink," which means, "say no more, I get the hint."

The whole phrase, here, may refer to a quote from Mohammed: "Prayer is better than sleep," where "a nod to the nabir" means "a prayer to the Prophet," and "wink" means sleep.
