How many times can you do Istikharah Prayer?

Question:

Salam,
Dear sheikh, how many times can you do Istikharah Prayer? I mean once week or daily and which time is the best for this prayer? Should one pray all five times or it doesn't matter?
Jazaka Allah Khayran

Answer:

Wa`alaykum As-Salaamu Warahmatullahi Wabarakatuh.

In the Name of Allah, Most Gracious, Most Merciful.

All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.

You can pray Istikharah as much as you want until to finish the task or mission you are doing Istikharah for. Nothing has been mentioned in the Sunnah regarding the best time for this Salah to be performed.

Allah Almighty knows best.
