Arabic original
اللَّهُمَّ إِنِّي أَسْأَلُكَ مِنَ الْخَيْرِ كُلِّهِ عَاجِلِهِ وَآجِلِهِ مَا عَلِمْتُ مِنْهُ وَمَا لَمْ أَعْلَمْ وَأَعُوذُ بِكَ مِنَ الشَّرِّ كُلِّهِ عَاجِلِهِ وَآجِلِهِ مَا عَلِمْتُ مِنْهُ وَمَا لَمْ أَعْلَمْ اللَّهُمَّ إِنِّي أَسْأَلُكَ مِنْ خَيْرِ مَا سَأَلَكَ عَبْدُكَ وَنَبِيُّكَ وَأَعُوذُ بِكَ مِنْ شَرِّ مَا عَاذَ بِهِ عَبْدُكَ وَنَبِيُّكَ
English translation
O Allah, I ask You from all that is good, in this world and in the hereafter, what I know and what I do not know. O Allah, I seek refuge with You from all evil, in this world and in the hereafter, what I know and what I do not know. O Allah, I ask You for the good that Your slave and Prophet has asked You for, and I seek refuge with You from the evil from which Your slave and Prophet sought refuge.
