Isthikhara

Narrated Jabir bin `Abdullah:

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. (Sahih ul bukhari ,kitaab ul tahjjud ,hadid 1166)
