What is the remedy for the slight ostentation (riya') or self-admiration (ʿujb) that may enter the soul despite striving for sincerity?

The cure for ostentation (riya') and self-admiration ('ujb) lies in striving against the self to repel what assails it. If one fails to do so, ostentation or self-admiration may overpower them and become the driving force behind their actions. This struggle is needed by everyone. It is difficult at first but eases later. Its cure is to uproot its roots and instantly repel whatever thoughts arise from it.
