The fact that in the historical and traditional sources there is no statement by Imam Zayn al-'Abidīn ('a) that implies the encouragement of Medinans to resist against the Syrian army or preventing them from revolt indicates that the Imam ('a) had not been able or had regarded as advisable to interfere in this event. But why indeed?
Did Imam Zayn al-'Abidīn ('a) not hold the required social position, after the tragedy of Karbala and the killing of majority of adherents of Imam Ali ('a) and the followers of ('a), to involve in the incident and viewed as futile to command the people of Medina to guide them to good and prohibit them from evil? Was the revolt of the inhabitants of Medina only religiously motivated or was it considered as a combination of religious, political, tribal, and economical motivations?
Or, why could not the interference of such spiritual figure as Imam Zayn al-'Abidīn ('a) in such complicated and multifaceted event be crucial and effective enough to be accepted and welcomed by the major trends of the time?
Was now Imam Zayn al-'Abidīn ('a) taking upon himself as his legal and social obligation to help out or prevent the Muhājirin and the Ansār , the reciters of Qur'an, the narrators of hadīth , and the companions of the Prophet (s) from the battle, that is those who, as he witnessed at close quarters to himself, with all their high status and position never assisted his grandfather 'Alī, his uncle Hasan b. 'Alī ('a), or his father Imam Husayn b.
'Alī ('a) and depended on their own understanding and knowledge in ups and downs of the incidents rather than on the ('a)? Or else, he did not feel obliged to accompany them due to the weakness of this movement, or did not prevent them because of their inadvisablity? Was Imam Zayn al-'Abidīn ('a) entangled in a political and social seclusion and pursuing monasticism? Or did he not have the morale for getting up again into conflict with the Umayyid ruling system?
Or did he firmly decide not to fight against the corruption of the rulers and their tyranny like the manner and lifestyle ( sīra ) of his grandfather 'Alī b. Abī Tālib ('a), his uncle Hasan b. 'Alī ('a), and his father Husayn b. 'Alī ('a)?!
