Can you please assist with the translation of the part in bold in the following narration?:

وعن عبد الله بن عمرو – رضي الله عنهما – قال: جاء رجل إلى رسول الله صلى الله عليه وسلم يستأذنه في الجهاد، فقال: (هل من والديك أحد حي؟ قال: أمي قال: انطلق فبرهما). فانطلق يحل الركاب


..’he proceeded to untie his saddle.’ 
(This illustrates the Sahabi (radiyallahu’anhu) changing his mind, and cancelling his journey for jihad)


And Allah Ta’ala Knows best,
