Shiavault - a Vault of Shia Islamic Books The Message Chapter 47: The Battle of Zatus Salasil From the day the Prophet migrated to Madina and made that city the centre of Islam, he was always watchful of the conditions of the enemies and their enthusiasm and conspiracies, and attached great importance to the collection of information about their activities.
He sent skillful and proficient persons to Makkah and to the different tribes of idolaters at various places so that they might inform him in time about the decisions and plots of the enemies. On becoming aware of their conspiracies he often nipped their plots in the bud. In such cases the warriors of Islam attacked the enemies unawares under the command of the Prophet or some brave officer of Islam and dispersed them before they could even move from their place.
As a result of this, Islam remained safe from the danger of the enemies, and much of the bloodshed was also avoided. In the present times information of the strength and fitness of the enemy and of his secret plans is considered to be one of the greatest factors contributing to victory, and the superpowers of the world possess extensive organizations for the training of spies and their dispatch and utilization.
In Islam initiative in this direction was taken by the Prophet himself, and after him the caliphs of Islam and specially the Commander of the Faithful also entrusted different duties to a number of spies. As and when he appointed someone as the governor of a locality he ordered some persons to watch his behaviour and activities and to submit reports to him (i.e. to Ali). He has alluded to this matter in a number of letters written to the governors in which they have been reprimanded.
(vide letters Nos. 33 and 45 in Nahjul Balaghah) In 2 A.H. the Prophet dispatched eighty persons from amongst the immigrants, under the command of Abdullah bin Jahsh, with instructions to encamp at a specified place and to inform him about the activities and schemes of Quraysh.
If the Prophet was not taken unawares at the time of the Battle of Uhud and concentrated his forces outside Madina before the arrival of the enemies and if, during the Battle of Ahzab, he dug a dreadful ditch in front of the enemies before they could reach there, it was entirely owing to the detailed reports which the Muslims, deputed for this purpose, submitted to him, and in this way performed their religious duty to save Islam from downfall.
