Istikhara dua and how to pray it

Part 1

اللَّهُمَّ إِنِّي أَسْتَخِيرُكَ بِعِلْمِكَ وَأَسْتَقْدِرُكَ بِقُدْرَتِكَ، وَأَسْأَلُكَ مِنْ فَضْلِكَ الْعَظِيمِ، فَإِنَّكَ تَقْدِرُ وَلاَ أَقْدِرُ وَتَعْلَمُ وَلاَ أَعْلَمُ وَأَنْتَ عَلاَّمُ الْغُيُوبِ

Allāhumma innī astakhīruka bi'ilmika wa astaqdiruka biqudratika wa as'aluka min faḍlikal-'aẓīm, fa innaka taqdiru wa lā aqdir, wa ta'lamu wa lā a'lam, wa anta 'allāmul-ghuyūb

O Allah, I ask You to guide me to what is best through Your knowledge, I ask You for strength through Your power, and I ask You of Your immense bounty. You are able and I am not; You know and I do not; and You are the Knower of all that is hidden.

Part 2 · at "hādhal-amr", think of your matter

اللَّهُمَّ إِنْ كُنْتَ تَعْلَمُ أَنَّ هَذَا الأَمْرَ خَيْرٌ لِي فِي دِينِي وَمَعَاشِي وَعَاقِبَةِ أَمْرِي فَاقْدُرْهُ لِي وَيَسِّرْهُ لِي ثُمَّ بَارِكْ لِي فِيهِ

Allāhumma in kunta ta'lamu anna hādhal-amra khayrun lī fī dīnī wa ma'āshī wa 'āqibati amrī, faqdurhu lī wa yassirhu lī thumma bārik lī fīh

O Allah, if You know that this matter is good for me in my religion, my livelihood and how my affairs turn out, then decree it for me, make it easy for me, and bless me in it.

Part 3

وَإِنْ كُنْتَ تَعْلَمُ أَنَّ هَذَا الأَمْرَ شَرٌّ لِي فِي دِينِي وَمَعَاشِي وَعَاقِبَةِ أَمْرِي فَاصْرِفْهُ عَنِّي وَاصْرِفْنِي عَنْهُ، وَاقْدُرْ لِي الْخَيْرَ حَيْثُ كَانَ ثُمَّ أَرْضِنِي بِهِ

Wa in kunta ta'lamu anna hādhal-amra sharrun lī fī dīnī wa ma'āshī wa 'āqibati amrī, faṣrifhu 'annī waṣrifnī 'anhu, waqdur liyal-khayra ḥaythu kāna thumma arḍinī bih

And if You know that this matter is bad for me in my religion, my livelihood and how my affairs turn out, then turn it away from me and turn me away from it, decree for me what is good wherever it may be, and make me content with it.
