SHAFAQNA – Does the leader of the Muslims always have to be a Ma’sum [infallible]? Ultimately, yes! How can one strive for perfection if ones’ ultimate leader is not a perfect servant of Allah? But how about in the time when the infallible Imam is in occultation? Shaykh Usama brilliantly presents the example of the Tawwabin- they ought to have followed Muslim Ibn Aqeel – a non-Ma’sum leader – but their failure to do so lead to the martyrdom of Imam Husayn [A]. The question for you now is: who is the Muslim Ibn Aqeel of today?
