Betraying Muslims and spying on them are among the worst sins and misdeeds, especially at times of war. In this hadeeth, Salamah ibn Al-Akwa‘ (may Allah be pleased with him) narrated that a disbelieving spy came to the Prophetﷺwhile he was on a journey. It was said that this took place during the battle of Hawaazin in 8 A.H., as recorded by Muslim. The Arabic word used in the hadeeth for spy is ‘Ayn, lit. an eye, because a spy’s job is mostly related to vision. The version of the hadeeth complied by Muslim stated that the spy came riding a red camel. He made it kneel down, extracted a strip of leather from its girth and tethered the camel with it. Then he began to eat with the people and look (curiously around). He ate with the Companions (may Allah be pleased with them) and talked with them so that he would not look suspicious. He started looking around and collecting the needed information. He learned that the Muslims were in a poor condition,in that some of them were on foot and had no riding animals. All of a sudden, he left hurriedly; he went to his camel, untethered it, made it kneel down, mounted it and urged the beast which ran off with him. The Prophetﷺsaid (to his Companions), “Chase and kill him.“ This was because leaving him unharmed would harm the Muslims, as he would convey information to the enemy and expose the Muslims’ weak points. This is contrary to messengers sent by the enemy; they may not be harmed as per the Islamic law, because they are bearers of peace and links of communication, and this reflects the beauty and graciousness of Islam. Salamah ibn Al-Akwa‘ (may Allah be pleased with him) chased and killed the spy. The Prophet ﷺ gave him all the spy’s belongings, arms, clothes, and riding animal. It is deduced from the hadeeth that it is allowable to kill awar spy if he comes to the Muslim lands and he is not given security. It is also inferred therefrom that the spoils of war taken from a killed spy belong to the one who kills him .
