The Prophet used to teach us the Istikhara for each and every matter as he used to teach us the Suras from the Holy Qur'an. (He used to say), "If anyone of you intends to do something, he should offer a two-rak`at prayer other than the obligatory prayer, and then say: 'Allahumma inni astakhiruka bi'ilmika, wa astaqdiruka biqudratika, wa as'aluka min fadlika-l-'azim, fa innaka taqdiru wala aqdiru, wa ta'lamu wala a'lamu, wa anta'allamu-l-ghuyub. Allahumma in kunta ta'lamu anna hadha-lamra khairun li fi dini wa ma'ashi wa 'aqibati `Amri (or said, fi 'ajili `Amri wa ajilihi) fa-qdurhu li, Wa in kunta ta'lamu anna ha-dha-l-amra sharrun li fi dini wa ma'ashi wa 'aqibati `Amri (or said, fi ajili `Amri wa ajilihi) fasrifhu 'anni was-rifni 'anhu wa aqdur li alkhaira haithu kana, thumma Raddani bihi," Then he should mention his matter (need).

The Prophet (p.b.u.h) used to teach us the way of doing Istikhara (Istikhara means to ask Allah to guide one to the right sort of action concerning any job or a deed), in all matters as he taught us the Suras of the Qur'an. He said, "If anyone of you thinks of doing any job he should offer a two rak`at prayer other than the compulsory ones and say (after the prayer): -- 'Allahumma inni astakhiruka bi'ilmika, Wa astaqdiruka bi-qudratika, Wa as'alaka min fadlika Al-`azlm Fa-innaka taqdiru Wala aqdiru, Wa ta'lamu Wala a'lamu, Wa anta 'allamu l-ghuyub. Allahumma, in kunta ta'lam anna hadha-lamra Khairun li fi dini wa ma'ashi wa'aqibati `Amri (or 'ajili `Amri wa'ajilihi) Faqdirhu wa yas-sirhu li thumma barik li Fihi, Wa in kunta ta'lamu anna hadha-lamra shar-run li fi dini wa ma'ashi wa'aqibati `Amri (or fi'ajili `Amri wa ajilihi) Fasrifhu anni was-rifni anhu. Waqdir li al-khaira haithu kana Thumma ardini bihi.' (O Allah! I ask guidance from Your knowledge, And Power from Your Might and I ask for Your great blessings. You are capable and I am not. You know and I do not and You know the unseen. O Allah! If You know that this job is good for my religion and my subsistence and in my Hereafter--(or said: If it is better for my present and later needs)--Then You ordain it for me and make it easy for me to get, And then bless me in it, and if You know that this job is harmful to me In my religion and subsistence and in the Hereafter--(or said: If it is worse for my present and later needs)--Then keep it away from me and let me be away from it. And ordain for me whatever is good for me, And make me satisfied with it). The Prophet added that then the person should name (mention) his need.

Ibn Maslamah and Ibn 'Isa reported from Muhammad b. al-Munkadir on the authority of Jabir.

As-Salami: Allah's Apostle used to teach his companions to perform the prayer of Istikhara for each and every matter just as he used to teach them the Suras from the Qur'an He used to say, "If anyone of you intends to do some thing, he should offer a two rak`at prayer other than the compulsory prayers, and after finishing it, he should say: O Allah! I consult You, for You have all knowledge, and appeal to You to support me with Your Power and ask for Your Bounty, for You are able to do things while I am not, and You know while I do not; and You are the Knower of the Unseen. O Allah If You know It this matter (name your matter) is good for me both at present and in the future, (or in my religion), in my this life and in the Hereafter, then fulfill it for me and make it easy for me, and then bestow Your Blessings on me in that matter. O Allah! If You know that this matter is not good for me in my religion, in my this life and in my coming Hereafter (or at present or in the future), then divert me from it and choose for me what is good wherever it may be, and make me be pleased with it."
