Al-Anfal - 8:61

وَإِن جَنَحُواْ لِلسَّلْمِ فَاجْنَحْ لَهَا وَتَوَكَّلْ عَلَى اللّهِ إِنَّهُ هُوَ السَّمِيعُ الْعَلِيمُ
[8:61]
And if they incline to peace, then incline to it and trust in Allah; surely He is the Hearing, the Knowing.
But if the enemy incline towards peace, do thou (also) incline towards peace, and trust in Allah: for He is One that heareth and knoweth (all things).
And if they incline to peace, incline thou also to it, and trust in Allah. Lo! He, even He, is the Hearer, the Knower.
