the last guy (cesar) who tabbed this was so badly wrong.

this is some of the song but i can't get the harmonics and the intro right.

heavy riff after intro
-----------------------------------------|
-----------------------------------------|
-----------------------------------------|  REPEAT UNTIL NAS STARTS RAPPING.
-----------------------------------------|
-----------------------------------------|
-3-3-0-0-1-0--0-0-1-0--------------------|

heavy verse riff
-----------------------------------------|
-----------------------------------------|
-----------------------------------------|  KEEP REPEATING THIS PATTERN UNTIL
-----------------------------------------|  NAS BREAKS INTO "TRUST NOBODY..".
-----------------------------------------|
-0-0-1-0--0-0-1-0--0-0-11-00--0-0-1-0----|

chorus riff
(one guitar plays this. cesar got the other riff right)
-----------------------------------------|
-----------------------------------------|
-----------------------------------------|  REPEAT UNTIL THE HEAVY VERSE RIFF
-2-2-3-2-5-2--2-3-2-5-2------------------|  STARTS AGAIN.
-2-2-3-2-5-2--2-3-2-5-2------------------|
-0-0-1-0-3-0--0-1-0-3-0------------------|

thats all i know but it's pretty accurate. the bass part follows the same pattern but is 
on a 5-string. this is played on standard tuning on a six stringer.
