[2:239] And if you are in fear, then standing, or mounted. But when you are secure, then remember God, as He taught you what you knew not.
i.e., 'Do not abandon intimate conversations with Me because of their [designated] times. I have enabled you [to do them in another way]. For truly I am the One Who gives power to the enemies you fear over you. But when you withdraw in your hearts through Me, their hands will be unable to reach you. I have appointed victory for you over them. Then when the fear is gone from you and you are secure, return to what you have established [in prayers], exerting your utmost in the times of your devotion in My presence, in private or in public'.
