Answered by Shaykh Faraz Rabbani
I just want to know whether the answer you may receive after reading istikhara is the best thing to do for *all* time, or if it is only the best thing to do for that *particular* point in time.

Walaikum assalam wa rahmatullah,
Istikhara (prayer of seeking guidance) gives the best answer, for one’s worldly and religious life (not worldly life alone), when coupled with another essential sunna: istishara (seeking sound counsel) of those worthy of being consulted and taking the sound means of assessing the situation at hand.
This is why it is good to consult with people of wisdom, understanding, and experience regarding the results of one’s prayer of seeking guidance (istikhara), because one’s own interpretation is often clouded by one’s inclinations and desires.
And Allah alone gives success.
Wassalam.
