"Istikhara" means to seek goodness from Allah, meaning when one intends to do an important task they do istikhara before the task. The one who does the istikhara is as if they request Allah Almighty that, O my Owner the Knower of Unseen guide me if this task is better for me or not?

Narrated Jabir bin 'Abdullah :The Prophet (Sallal Laho Alaihi Wasallam) used to teach us the way of doing Istikhara, in all matters as he taught us the Suras of the Quran. He said, "If anyone of you thinks of doing any job he should offer a two Rakat prayer (First pray two cycles of ritual prayer [rakaat] such that in the first rakat after Surah Fateha (Allhamd …) recite Surah al-Kafirun and in the second rakat after Surah Fatiha (Allhamd…) recite Surah al-Ekhlaas and after finishing prayer [salam] then recite this Dua [ "O Allah! I seek goodness from Your Knowledge and with Your Power (and Might) I seek strength, and I ask from You Your Great Blessings, because You have the Power and I do not have the power. You Know everything and I do not know, and You have knowledge of the unseen. Oh Allah! If in Your Knowledge this action (which I intend to do) is better for my religion and faith, for my life and end [death], for here [in this world] and the hereafter then make it destined for me and make it easy for me and then add blessings [baraka'] in it, for me. O Allah! In Your Knowledge if this action is bad for me, bad for my religion and faith, for my life and end [death], for here [in this world] and the hereafter then turn it away from me and turn me away from it and whatever is better for me, ordain [destine] that for me and then make me satisfied with it."]) other than the compulsory ones. Ref.: Bukhari Sharif.

Hazrat Saheballah said that when anybody faces problem, unable to decide whether certain has to be done or no,to get the answers of your questions.

Note: - The condition is to say this prayer as the last thing before going to bed. The person must go to bed with wuzu without conversing with anyone after reciting this prayer. Lie down and fall asleep on the right side of the body. Continue this procedure for 7 to 11 days only to achieve your Ambition as early as possible. Insha'Allah. Incase if you do not dream, and the thought that strongly reflects again and again say Bismillah and follow that thought, Because that is indirectly the answer from the Almighty Allah.
