The realization of change in an Islamic sense is impossible...
The realization of change in an Islamic sense is impossible so long as this power was not shored up by a popular base conscious of the goals of power, believing in its theory of governance, acting to defend it, explaining its stances to the larger populace and braving the storms. Midway through the first century after the Prophet's death, the Shiite leadership, shunned from power, sought constantly to return to rule in the ways it deemed proper.
It was convinced of the existence of popular bases of consciousness, or vigilant Muhajirin, Ansar and all those who emulated their best actions. However, half-a-century later, when little remained of these popular bases, and with indecisive generations[^5] newly emerging under the influence of deviationism, the accession to power by the Shiite movement would never have achieved the larger goal; the popular bases that reinforced consciousness and sacrifice no longer existed.
In the face of this situation, there were only two possible avenues for action: One, action for the sake of rebuilding the popular and conscious bases that could properly pave the way to a transfer of power. Two, stirring the Islamic Ummah's conscience and will; safeguarding some degree of life and stalwartness to fortify the Ummah against abdicating unconditionally its identity and honour to deviationist rulers.
The first option was the one chosen by the Imams themselves; whereas the second was taken by the revolutionary partisans of 'Ali as they sought through fearless sacrifice to sustain the Islamic conscience and will. The Imams used to support the more sincere among them. Imam `Ali b. Musa al-Rida once said to Caliph Ma'mun, in reference to Zayd b. `Ali al-Shahid, that he was one of the learned from the House of Muhammad.
He was angered for the sake of God, fought enemies until he was killed in God's way. Abu Mus'a b. Ja`far has related to me that he heard his father Ja'far b. Muhammad say: “May God have merry on my uncle Zayd. He made summons on behalf of al-Rida, of the House of Muhammad. Had he triumphed, he would have fulfilled his promise. Zayd b. `Ali did not call what was not in his right to do so. He was more heedful toward God than that.
