What are the limits of tolerance, and is it permissible to be tolerant in all matters?

Lexically, tolerance means generosity and bounty. It is the act of forgiving an offender and an oppressor. This forgiveness is permissible without limits; indeed, it is often the preferred course of action in many situations. This is exemplified in the verse: "The recompense for an evil deed is an evil deed of similar proportion; but whoever pardons and makes reconciliation - his reward is due from Allah. Indeed, He does not like wrongdoers." However, in some cases, not forgiving or tolerating might be better.
