I agree with Ryan's post, but will take it one step further.
For hallways and interior stairways of 6 or more risers, I require a lighting fixture of some kind, even if it is only a 'lamp holder' such as a keyless porcelain.
The reasoning that a 'fixture' is not required would also mean that receptacles in the 'receptacle outlet' (the box installed to receive the receptacle) would not be required at a final.
210.52. Dwelling Unit Receptacle Outlets. This section provides requirements for 125- volt, 15- an 20- amp receptacle outlets.
