I've been an on and off Muslim. I sometimes become very steadfast in my prayers, refrain from sins, do proper Taubah etc. Then I still don't feel this 'inner peace' that everyone talks about. Feeling calm and loved by Allah etc. It feels so robotic even though my intentions are to please Allah.
Then I just revert to doing what people in West do such as drinking, not saying my prayers etc.
Is it true that if you completely follow Islam you should feel at peace, blessed and loved? Is this just relative or is there actually some Quranic verse or Hadees that says such a feeling would be granted?
