SHAFAQNA – It is narrated from Imam Hassan Askari (AS) who explained the ways in which a believer can become the most devout person: The most pious person is the one who when is in doubt, stops. The most devout person is the one who performs the obligatory duties (Wajebat of the religion). The most ascetic of the people is the one who gives up Haram. The most committed of the people is the one who abandons sins [1].
