Salatul_Istikharah نماز إستخاره

When a person wishes to carry out some important work,guidance should be sought from Allah.The Prophet peace be upon him has mentioned that a person who does not seek guidance from Allah and does not carry out Istikharah is deprived of good and is unfortunate.There will be no regret if Istikharah is made before accepting a proposal for marriage, travel,important business or any other important tasks.Perform two Rak'aats.Thereafter recite the following Du'aa:
اللَّهُمَّ إِنِّي أَسْتَخِيرُكَ بِعِلْمِكَ وَأَسْتَقْدِرُكَ بِقُدْرَتِكَ، وَأَسْأَلُكَ مِنْ فَضْلِكَ الْعَظِيمِ، فَإِنَّكَ تَقْدِرُ وَلاَ أَقْدِرُ وَتَعْلَمُ وَلاَ أَعْلَمُ وَأَنْتَ عَلاَّمُ الْغُيُوبِ، اللَّهُمَّ إِنْ كُنْتَ تَعْلَمُ أَنَّ هَذَا الأَمْرَ خَيْرٌ لِي فِي دِينِي وَمَعَاشِي وَعَاقِبَةِ أَمْرِي فَاقْدُرْهُ لِي وَيَسِّرْهُ لِي ثُمَّ بَارِكْ لِي فِيهِ، 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
Upon reaching the word هذا الأمرt think the reason and work for which Istikharsh is being made.The Istikharah salah should be continued untill the task is firm on which the Istikhrah is carried out heartly or mentaly,mostly till seven days,rarely to a month.

Istikharh should not be performed about the following matters:

Istikharah should not be done for performing a mandatory or Fardh duty,as should I perform Haj or not.Istikharah should rather be made to determine the time of travel for Haj,eg.When should I travel for Haj?
