Prayer for complete trust in God

Hazrat Abdullah bin Abbas^ra relates that the Holy Prophet^sa routinely recited this prayer.

اَللّٰھُمَّ لَکَ اَسْلَمْتُ وَبِکَ آمَنْتُ وَعَلَیْکَ تَوَکَّلْتُ وَاِلَیْکَ أَنَبْتُ وَبِکَ خَاصَمْتُ اَللّٰھُمَّ اِنِّی أَعُوذُ بِعِزَّتِکَ لَا اِلٰہَ اِلَّا اَنْتَ أَنْ تُضِلَّنِی أَنْتَ الْحَیُّ الَّذِی لَا یَمُوتُ وَالْجِنُّ وَالْاِنْسُ یَمُوتُونَ

“O Allah, I have entrusted everything unto You, believe in You, trust in You and am inclined towards You. With Your name, I face the enemy. O Allah, I seek refuge in Your honour. There is none worthy of worship except You. Do not lead me astray. You are the Ever Living Being Who is Immortal, while human beings and jinns will perish ultimately.”

(Sahih Muslim, Kitab al-Zikr)
