Dua for Salat al-Istikhara

"Allahumma inni astakhiruka bi 'ilmika, wa astaqdiruka bi qudratika, wa as'aluka min fadlika al-'azim. Fa innaka taqdiru wa la aqdiru, wa ta'lamu wa la a'lamu, wa anta 'allamul-ghuyub. Allahumma in kunta ta'lamu anna hadhal-amra khayrun li fi deeni wa ma'ashi wa 'aqibati amri, faqdurhu li wa yassirhu li, thumma barik li fih. Wa in kunta ta'lamu anna hadhal-amra sharrun li fi deeni wa ma'ashi wa 'aqibati amri, fasrifhu 'anni wasrifni 'anhu, waqdur liyal-khayra haythu kana, thumma ardini bih."

Translation

"O Allah! I seek goodness from You through Your knowledge, and I seek strength from You through Your power, and I ask You from Your immense favor. For You have power, and I have no power. You know, and I do not know, and You are the Knower of the unseen. O Allah, if You know that this matter is good for me in my religion, my livelihood, and the outcome of my affairs, then decree it for me, make it easy for me, and bless it for me. And if You know that this matter is bad for me in my religion, my livelihood, and the outcome of my affairs, then turn it away from me and turn me away from it. And decree for me what is good wherever it may be, and make me content with it." .
