10.)
اللَّهُمَّ أَسْلَمْتُ نَفْسِي إِلَيْكَ، وَوَجَّهْتُ وَجْهِي إِلَيْكَ، وَفَوَّضْتُ أَمْرِي إِلَيْكَ، وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ، رَغْبَةً وَرَهْبَةً إِلَيْكَ، لاَ مَلْجَأَ وَلاَ مَنْجَأَ مِنْكَ إِلَّا إِلَيْكَ، آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ، وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ
O Allâh, I have entrusted my life to You, turned my face to You, entrusted all my affairs to You, and have totally placed my reliance on You. All this I do to gain Your mercy and out of fear for Your punishment. There is no protection from Your wrath except through Your mercy. I believe in Your book which You have revealed and in Your apostle which You have sent. (Bukhârî)
