This work uses (c)-comparison functions in a metric space endowed with an arbitrary binary relation to establish certain fixed point results under a nonlinear version of almost contractions. The findings addressed here generalize and extend a number of recent findings. A few scenarios are described to demonstrate the validity of our results. The legitimacy of the unique solution of a nonlinear integral problem is assessed utilizing our findings.
