Al-Adab Al-Mufrad #705

Jabir said, "The Prophet. may Allah bless him and grant him peace, used to teach us the istikhara in matters just as if it was a sura of the Qur'an. He said, 'When someone is concerned about something, he should pray two rak'ats and then say, 'O Allah, I ask You for the good by Your knowledge and I ask You for strength by Your power and I ask You for some of Your immense abundant favour, You have the power and I do not. You know and I do not know. You are the Knower of the Unseen Worlds. O Allah, if You know that this affair is good for me in my deen, my livelihood and the end of my affair (or he said 'in the beginning of my affair') and its conclusion, then avert it from me and avert me from it. Decree for me the good wherever it is and then make me content." Then he should state what he needs.'"
