The Prayer of Seeking Guidance (Istikhara)

Mu'awiya ibn Maythara narrated that Imam عليه السلام said: "No servant who performs istikhara (seeks Allah’s سبحانه وتعالى guidance) seventy times with this istikhara will be left without Allah سبحانه وتعالى, the Mighty and Majestic, granting him guidance." The supplication is: "O’ the best of those who see, O’ the most hearing of the hearers, O’ the swiftest of reckoners, O’ the most merciful of the merciful, O’ the wisest of judges, send blessings upon Muhammad and his family and guide me in such and such matter."
