اللَّهُمَّ إِنِّي أَسْتَخِيرُكَ بِعِلْمِكَ، وَأَسْتَقْدِرُكَ بِقُدْرَتِكَ، وَأَسْأَلُكَ مِنْ فَضْلِكَ الْعَظِيمِ، فَإِنَّكَ تَقْدِرُ وَلَا أَقْدِرُ، وَتَعْلَمُ وَلَا أَعْلَمُ، وَأَنْتَ عَلَّامُ الْغُيُوبِ
Allāhumma innī astakhīruka bi-ʿilmik, wa astaqdiruka bi-qudratik
O Allah, I seek Your guidance by Your knowledge and Your power, and I ask You from Your immense bounty. For You are able and I am not, You know and I do not, and You are the Knower of the unseen. (After two rakʿah when facing a decision.)
