There's no priesthood in Islam.

Excellent question! In Islam, since there are no clerics in Islam, all Muslims are called to be leaders in their society.

There's a Litmus Test to verify the quality of Leadership..and it is ...

A True leader will never prefer Hadith over Quran.

A True Leader do not insists/impose his/her opinion..and never offers a package of beliefs to follow as some prominent leaders of Islam are doing..at some sites.

Dis-agreements in Islamic issues contribute towards the 'Health and Security' of Islamic societies.

Islam encourages everyone to strive for knowledge of the Religion...and lead others, justfully!
