Hi everyone,
I have converted an rgb image to gray scale and then applied adaphisteq to enhance its' contrast. Now I want to get the R,G,B components of this image. Is it possible b/c now that we have converted it to gray scale and enhanced it?

No. You can only get the color from the original color image, not
from a monochrome version of it.

You can get to the result you are looking for by transforming your colour image into HSV colour format, then applying your processing to the V plane, then reconstruct the HSV image using the adjusted V plane to replace the old one, and then reconvert back to RGB.

Alternatively see the following thread

Hope that helps
