Most of the pronunciations on the interwebs are terrible and wrong. "Na'ir" rhymes with far, but it's not exactly that, there's a different vowel before the 'r'. Sort of like an very quick 'i/e' sound. NAA-er would come closest, I suppose. "Al" rhymes with 'cull' (as in controlling herd populations of animals). "Saif" has the same "ai" sound as 'lair', with 's' and 'f' pronounced normally.
