اللّهُـمَّ إِنَّـي أَسْـأَلُـكَ خَيْـرَها، وَخَيْـرَ ما فيهـا، وَخَيْـرَ ما اُرْسِلَـتْ بِه، وَأَعـوذُ بِكَ مِنْ شَـرِّها، وَشَـرِّ ما فيهـا، وَشَـرِّ ما اُرْسِلَـتْ بِه
Allāhumma innī as'aluka khayrahā, wa khayra mā fīhā, wa khayra mā ursilat bih, wa a`ūdhu bika min sharrihā, wa sharri mā fīhā, wa sharri mā ursilat bih.
O Allah, I ask You for the good of it, for the good of what it contains, and for the good of what is sent with it. I seek refuge in You from the evil of it, from the evil of what it contains, and from the evil that is sent with it.
Muslim 2/616, Al-Bukhari 4/76.
