About himself Amir al-mu'minin says, that "We do not threaten the enemy before battle, nor utter boasts, nor terrorise the enemy by raising unnecessary cries because it is not the way of the brave to use the tongue instead of the hand." That is why on this occasion he said to his comrades: "Beware of excessive talk as it is cowardice."
