Ibnul Mutahhir (a raafidi) said that Imaamah is the most important obligation.
Response: This is a lie according to the consensus of the scholars, for Imaan [i.e. belief in Allaah; belief in Allaah’s Angels; belief in Allaah’s Books; belief in Allaah’s Messengers; belief in the hereafter and belief in Qadr-its good and evil)] is more important. And from those affairs that are known by everyone in the religion is that when the disbelievers during the era of Messenger entered into the fold of Islaam, the rulings of Islaam were conveyed to them and Imaamah was not mentioned to them in any situation. Then how can it be the most important obligation?!
