اللَّهُمَّ إِنَّا نَسْأَلُكَ بِأَسْمَائِكَ الْحُسْنَى وَكَلِمَاتِكَ التَّامَّاتِ مَا عَلِمْنَا مِنْهَا وَمَا لَمْ نَعْلَمْ، أَنْ تَغْفِرَ لَنَا وَلِأَحْبَابِنَا أَبَدًا وَلِلْمُسْلِمِينَ كُلَّ ذَنْبٍ، وَتَسْتُرَ لَنَا كُلَّ عَيْبٍ، وَتَكْشِفَ عَنَّا كُلَّ كَرْبٍ، وَتَصْرِفَ وَتَرْفَعَ عَنَّا كُلَّ بَلَاءٍ، وَتُعَافِيَنَا مِنْ كُلِّ مِحْنَةٍ وَفِتْنَةٍ وَشِدَّةٍ فِي الدَّارَيْنِ، وَتَقْضِيَ لَنَا كُلَّ حَاجَةٍ فِيهِمَا، يَا مَنْ هُوَ اللَّهُ الَّذِي لَا إِلَهَ إِلَّا هُوَ، يَا عَالِمَ الْغَيْبِ وَالشَّهَادَةِ سُبْحَانَكَ لَا إِلَهَ إِلَّا أَنْتَ يَا ذَا الْجَلَالِ وَالْإِكْرَامِ، أَسْأَلُكَ بِاسْمِكَ الْأَعْلَى الْأَعَزِّ الْأَجَلِّ الْأَكْرَمِ يَا ذَا الْجَلَالِ وَالْإِكْرَامِ وَالْمَوَاهِبِ الْعِظَامِ

O Allah, we ask You by Your beautiful names and Your perfect words, those we know and those we do not know, to forgive us, our loved ones forever, and all Muslims from every sin. We ask You to cover every defect, relieve every distress, and lift every affliction. Grant us safety from every ordeal, trial, and hardship in both worlds, and fulfill every need in them. O You who are Allah, there is no god but He, Knower of the unseen and the witnessed, glory be to You, there is no god but You, O Possessor of Majesty and Honor. I ask You by Your Supreme, Most Mighty, Most Majestic, Most Generous Name, O Possessor of Majesty and Honor and great gifts.
