In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Ka’b Bin Malik, may Allah be pleased with him, said: “When the Prophet, peace and blessings of Allah be upon him, intended to go on an expedition (against a people with whom there is no treaty and war was declared), he always pretended to be going somewhere else, and he would say, ‘War is stratagem'”. [1]

Imam at-Tabari, may Allah have mercy upon him, said: “To give a wrong impression – during war – through Mu’aaradah [i.e. making one’s statements or actions obscure (ambiguous) to mislead the opponent about one’s real plans] is allowed”. [2]

Ibn al-Arabi Al-Maliki, may Allah have mercy upon him, said, “Stratagem during war takes place through concealment and giving a wrong impression (to the opponent)”. [3]

The scholars unanimously agree that it is permissible to deceive the unbelievers (i.e. when a Muslim country declares war), but this is not permissible if it violates a covenant or an agreement that was made for a guarantee of safety. [4]

However, stratagem does not necessitate treachery. Abu Al-l Fayd, may Allah have mercy upon him, narrated that Sulaym Ibn Amir, may Allah have mercy upon him, reported that there was a peace treaty between Mu’aawiyah, may Allah be pleased with him and his father, and the Byzantines. He was marching towards their country and when the covenant came to an end, he would attack them. A man came on a horse, saying, “Allah is the Most Great! Allah is the Most Great! Let there be fulfillment and not treachery!” Mu’aawiyah sent for him and questioned him about that. He said: “I heard Allah’s Messenger, peace and blessings of Allah be upon him, say, “When one has a covenant with people he must not strengthen or loosen it until its term comes to an end or he brings it to an end in agreement with them”. He said, “So Mu’aawiyah returned with the people”. [5]

Abdullah Ibn Umar, may Allah be pleased with him and his father, reported that Allah’s Messenger, peace and blessings of Allah be upon him, said: “When Allah gathers the earlier and later generations on the Day of Resurrection, He will raise a banner for every treacherous person and it will be announced that this is the treachery of this person, the son of this person”.
