Istikhāra (consultation of Allah)

اللَّهُمَّ إِنِّي أَسْتَخِيرُكَ بِعِلْمِكَ، وَأَسْتَقْدِرُكَ بِقُدْرَتِكَ، وَأَسْأَلُكَ مِنْ فَضْلِكَ الْعَظِيمِ، فَإِنَّكَ تَقْدِرُ وَلَا أَقْدِرُ، وَتَعْلَمُ وَلَا أَعْلَمُ، وَأَنْتَ عَلَّامُ الْغُيُوبِ. اللَّهُمَّ إِنْ كُنْتَ تَعْلَمُ أَنَّ هَذَا الْأَمْرَ خَيْرٌ لِي فِي دِينِي وَمَعَاشِي وَعَاقِبَةِ أَمْرِي فَاقْدُرْهُ لِي وَيَسِّرْهُ لِي ثُمَّ بَارِكْ لِي فِيهِ، وَإِنْ كُنْتَ تَعْلَمُ أَنَّ هَذَا الْأَمْرَ شَرٌّ لِي فِي دِينِي وَمَعَاشِي وَعَاقِبَةِ أَمْرِي فَاصْرِفْهُ عَنِّي وَاصْرِفْنِي عَنْهُ، وَاقْدُرْ لِي الْخَيْرَ حَيْثُ كَانَ ثُمَّ أَرْضِنِي بِهِ

Allāhumma innī astakhīruka bi-ʿilmik, wa astaqdiruka bi-qudratik, wa as'aluka min faḍlika-l-ʿaẓīm, fa-innaka taqdiru wa lā aqdir, wa taʿlamu wa lā aʿlam, wa anta ʿallāmu-l-ghuyūb. Allāhumma in kunta taʿlamu anna hādha-l-amra khayrun lī fī dīnī wa maʿāshī wa ʿāqibati amrī fa-qdurhu lī wa yassirhu lī thumma bārik lī fīh, wa in kunta taʿlamu anna hādha-l-amra sharrun lī fī dīnī wa maʿāshī wa ʿāqibati amrī fa-ṣrifhu ʿannī wa-ṣrifnī ʿanh, wa-qdur liya-l-khayra ḥaythu kāna thumma arḍinī bih.

O Allah, I seek Your counsel by Your knowledge and Your ability by Your power, and I ask You of Your immense grace. You are able and I am not, You know and I do not, and You are the Knower of the unseen. O Allah, if You know that this matter is good for me concerning my religion, my life, and the outcome of my affair, then decree it for me, facilitate it for me, and bless it for me. But if You know that it is evil for me, then avert it from me and avert me from it, and decree for me good wherever it may be, and then make me pleased with it.
