O Believers! Whenever the Messenger (blessings and peace be upon him) calls you for some assignment that brings you (eternal) life, present yourselves (immediately), responding to Allah and His Messenger (blessings and peace be upon him) with submissiveness and obedience. And bear in mind that Allah intervenes between man and his heart (with a Glory of exclusive nearness), and that all of you will (ultimately) be gathered towards Him.
