What is the concept of halal & haram in Ismailism?

For Ismaili Muslims, the present Imam is the authoritative interpreter of Islam and he guides the community in every time as to what is halal and haram - just as Prophet Muhammad did so in his lifetime. Currently, the following are haram for Ismailis based on the Imam’s guidance:

• drinking alcohol
• smoking
• drugs
• eating pork
• lying 
• cheating
• backbiting
• dressing immodestly
• other unethical activities

The concept of halal is extended to one’s spirituality. Practicing virtue regularly leads to a halal life.
