1-Is it permissible to pray behind an imam whose actions you are displeased with?

To determine the permissibility of following an Imam, one must first understand the actions that displease the questioner. If the dissatisfaction pertains to worldly matters, it does not affect the permissibility of following him. However, if it relates to religious matters, then he should be guided, as we clarified in Fatwa number: 32917.
