Is it necessary to change one's place between the Shaf' and Witr prayers?

It is recommended for the worshipper to move from the spot where he completed his prayer (whether obligatory or supererogatory) in order to increase the places of prostration that will bear witness for him, and to enliven places with worship. If he does not move, he should separate with human speech. Accordingly, it is recommended to change place after the Shaf‘ (even-numbered) rak‘ahs before the Witr (odd-numbered) rak‘ah.
