When conditions demand vigilance because of war in which Islam has indulged itself the dire necessity becomes protection and safety of Islam. In such a case Imam would have an immediate and direct contact with the Caliph besides his advice for saving Muslims. But conditions differ. In reality, Umar had started war all by himself without consulting the Imam or taking his advice. The Caliph had done it by his own stubbornness.
In such conditions wherein there is no alternative but to send troops necessity dictates some provisionary measures to minimize danger which is certain or to avert uprooting blow from hitting Muslims and Islam. Therefore we see the Imam anxious and worried. Else he has no other reason. It was not and cannot be his approval of battles. In other words, the wrong, rather insane decisions in military issues cause the Caliph’s life to be in the mortgage of Islam, i.e. protection of Islam.
In such an event, there is no way out but to dispense the best advice for the sake of avoiding reversion to infidelity and saving religion from being wiped out completely. Imam Ali (a.s.) did not pay any importance to Caliph’s life if that life was to bring back past ignorant days of idol worship. Ali had warned Umar: If the Caliph does not repent and does not give up the design to revert masses to the old days of infidelity and idol worship I will cut off his head.
[1] There is a great difference between the two attitudes of Imam Ali (a.s.). According to his behavior we come to know that the life of Caliph in ordinary circumstances is not of any extra value or worth. Its value comes to worth only in case of its having an immediate link to Islam’s safety or that its end spells Islam’s end too.
The dread of returning to infidelity of Muslim society or a likelihood of grip of idol worship upon the society makes a Caliph’s life worthy or attaches a corresponding worth to it. Therefore consultation of Ali (a.s.) in military affairs is not a sign of good relations. It does not establish any good terms on either side. So how can it be drawn in the sense of his approval of their Caliphate, or his acknowledgement of their government?
