Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) said: "The best companions are four, and the best army is the one that has four thousand men, and the best detachment (military unit) is the one that has four hundred men, and if the number reaches twelve thousand and they act with patience and truthfulness, they will not be overcome due to being few."
