وَإِن جَنَحُوا لِلسَّلْمِ فَاجْنَحْ لَهَا)) (And if they incline to peace, then incline to it.): Islam is the religion of peace, so if they turn and incline towards peace, then you should also incline towards it.

(وَتَوَكَّلْ عَلَى اللَّهِ ۚ) (and rely upon Allah,): you must also put your trust in Allah (swt). However, you must also put your trust in Allah (swt) with this inclination towards peace, since they may plot something in secret and covertly and this could be a form of deceit. Hence you must put your reliance on Allah (swt).

(إِنَّهُ هُوَ السَّمِيعُ الْعَلِيمُ) (Indeed, it is He who is the Hearing, the Knowing.): Surely, Allah (swt) is the All-Hearing and All-Knowing; He knows what the hearts conceal.
