This is just wrong AFAICT. Where'd you get it from?
Also, I giggled when I heard this line of a Hindi/Urdu song:
- "Kar de idhar bhi tu nigaahein" (I believe it means "have a look at me, as well")
niggaahein apparently means "look", but it just sounds like "ni**a, hey!" to me.
Nigaah means 'look', and nigaahein [nɪˈgaɦẽ] is the plural form. It's a loanword from Persian نگاه, which is of course related to the verb stem Vlürch mentioned.
This is the third time these words are being brought up in this thread.
