“When the Prophet (SAW) died, there was a man in Al-Madinah who used to make a niche in the grave and another who used to dig graves without a niche. They said: ‘Let us pray Istikharah to our Lord and call for them both, and whichever of them comes first, we will let him do it.’ So they were both sent for, and the one who used to make the niche-grave came first, so they made a niche-grave for the Prophet (SAW).”

“The Messenger of Allah (saw) used to teach us Istikharah, just as he used to teach us a Surah of the Qur’an. He said: ‘If anyone of you is deliberating about a decision he has to make, then let him pray two Rak’ah of non- obligatory prayer, then say: Allahumma inni astakhiruka bi ‘ilmika wa astaqdiruka bi qudratika wa as’aluka min fadlikal-‘azim, fa innaka taqdiru wa la aqdir, wa ta’lamu wa la a’lam, wa Anta ‘allamul-ghuyub. Allahumma in kunta ta’lamu hadhal-amra (then the matter should be mentioned by name) ma kan min shay’in khairan li fi dini wa ma’ashi wa ‘aqibati amri, aw khairanli fi ‘ajili amri wa ajilihi, faqdurhu li wa yassirhu li wa barik li fihi. Wa in kunta ta’lamu [O Allah, I seek Your guidance (in making a choice) by virtue of Your knowledge, and I seek ability by virtue of Your power, and I ask You of Your great bounty. You have power, I have none. And You know, I know not. You are the Knower of hidden things. O Allah, if in Your knowledge, this matter (then it should be mentioned by name) is good for me in my religion, my livelihood and my affairs, or both in this world and in the Hereafter then ordain it for me, make it easy for me, and bless it for me. And if in Your knowledge]. Then saying similar to what he said the first time, except: Wa in kana sharran li fasrifhu ‘anni wasrifni ‘anhu waqdur li al-khair haithuma kana thumma raddini bihi (If it is bad for me then turn it away from me and turn me away from it, and ordain for me the good wherever it may be and make me pleased with it).’”

"The Messenger of Allah used to teach his Companions to perform Istikharah in all matters, just as he used to teach them Surahs from the Qur'an. He said: 'If any one of you is deliberating about a decision he has to make, then let him pray two Rak'ahs of non-obligatory prayer, then say: Allahumma inni astakhiruka bi 'ilmika wa astaqdiruka bi qudratika wa as'aluka min fadlika, fa innaka taqdiru wa la aqdir, wa ta'lamu wa la a'lam, wa anta 'allam al-ghuyub. Allahumma in kunta ta'lamu anna hadhal-amra khayrun li fi dini wa ma'ashi wa aqibati amri faqdurhu li wa yassirhu li thumma barik li fihi. Allahumma, wa in kunta ta'lamu annahu sharrun li fi dini wa ma'ashi wa 'aqibati amri fasrifhu 'anni wasrifni 'anhu waqdur li al-khayr haythu kana, thumma radini bihi. (O Allah, I seek Your guidance (in making a choice) by virtue of Your knowledge, and I seek ability by virtue of Your power, and I ask You of Your great bounty. You have power, I have none. And You know, I know not. You are the Knower of hidden things. O Allah, if in Your knowledge, this matter (then it should be mentioned by name) is good for me in my religion, my livelihood and my affairs (or: both in this world and in the Hereafter), then ordain it for me, make it easy for me, and bless it for me. And if in Your knowledge it is bad for me and for my religion, my livelihood and my affairs (or: for me both in this world and the next), then turn it away from me and turn me away from it, and ordain for me the good wherever it may be and make me pleased with it.)"

Messenger of Allah (PBUH) used to teach us the Istikharah (seeking guidance from Allah) in all matters as he would teach us a Surah of the Qur'an. He used to say: "When one of you contemplates entering upon an enterprise, let him perform two Rak'ah of optional prayer other than Fard prayers and then supplicate: "Allahumma inni astakhiruka bi 'ilmika, wa astaqdiruka bi qudratika, wa as-'aluka min fadlikal-'azim. Fainnaka taqdiru wa la aqdiru, wa ta'lamu wa la a'lamu, wa Anta 'allamul- ghuyub. Allahumma in kunta ta'lamu anna hadhal-'amra (and name what you want to do) khairun li fi dini wa ma'ashi wa 'aqibati amri, (or he said) 'ajili amri ajilihi, faqdurhu li wa yassirhu li, thumma barik li fihi. Wa in kunta ta'lamu anna hadhal 'amra (and name what you want to do) sharrun li fi dini wa ma'ashi wa 'aqibati amri, (or he said) wa 'ajili amri wa ajilihi, fasrifhu 'anni, wasrifni 'anhu, waqdur liyal- khaira haithu kana, thumma ardini bihi." (O Allah, I consult You through Your Knowledge, and I seek strength through Your Power, and ask of Your Great Bounty; for You are Capable whereas I am not and, You know and I do not, and You are the Knower of hidden things. O Allah, if You know that this matter (and name it) is good for me in respect of my Deen, my livelihood and the consequences of my affairs, (or he said), the sooner or the later of my affairs then ordain it for me, make it easy for me, and bless it for me. But if You know this matter (and name it) to be bad for my Deen, my livelihood or the consequences of my affairs, (or he said) the sooner or the later of my affairs then turn it away from me, and turn me away from it, and grant me power to do good whatever it may be, and cause me to be contented with it). And let the supplicant specify the object."
