Mishkat al-Masabih 19 Jihad كتاب الجهاد 256

عَن المِسْوَرِ وَمَرْوَانَ: أَنَّهُمُ اصْطَلَحُوا عَلَى وَضْعِ الْحَرْبِ عَشْرَ سِنِينَ يَأْمَنُ فِيهَا النَّاسُ وَعَلَى أَنَّ بَيْنَنَا عَيْبَةً مَكْفُوفَةً وَأَنَّهُ لَا إِسْلَالَ وَلَا إِغْلَالَ. رَوَاهُ أَبُو دَاوُد

Al-Miswar and Marwan said they agreed to abandon war for ten years during which the people would have security, on the basis that there should be sincerity between them and that there should be no theft or treachery. Abu Dawud transmitted it.
