If you photograph people with it, handheld, the answer is: no. Generally people move, and you need to have a shutter speed as fast as the inverse focal length rule indicates, as a minimum. For kids it often needs to be twice as fast.
So, if shooting people in low light is the aim, use a reasonable aperture (F/2 maybe), and just up the iso up to a point where you get at least 1/50 s on FF or 1/80 s on APS-C.
With good technique as indicated by John you may be able to use longer shutter speeds, but to be very honest, it will be very hard to get sharp pictures of people with longer shutter speeds, because they often move to much.
For anything static, you can use the same technique, or use a tripod, of course, if you get into longer shutter speeds.
