وَإِن جَنَحُوا لِلسَّلْمِ فَاجْنَحْ لَهَا وَتَوَكَّلْ عَلَى اللَّهِ إِنَّهُ هُوَ السَّمِيعُ الْعَلِيمُ

If they incline to peace, then incline to it and rely upon Allah. Verily, it is He who is the Hearing, the Knowing.

Surah Al-Anfal 8:61
-------------------
Ali ibn Abu Talib reported: The Messenger of Allah, peace and blessings be upon him, said:

إِنَّهُ سَيَكُونُ بَعْدِي اخْتِلَافٌ أَوْ أَمْرٌ فَإِنْ اسْتَطَعْتَ أَنْ تَكُونَ السِّلْمَ فَافْعَل

Verily, after me there will be conflicts or affairs, so if you are able to end them in peace, then do so.
