Power to stay execution

If at any time it appears to the satisfaction of the magistrate that any party to an action is unable from sickness or other sufficient cause to pay and discharge the amount of any judgment given against him, or any instalment thereof, the magistrate may in his discretion suspend or stay any judgment given or execution issued in such action, for such time and on such terms as the magistrate thinks fit, and so from time to time until it appears that such cause of inability has ceased. etc.
