Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) relates that whenever the young men of his household passed by the Messenger of Allah (peace and blessings be upon him), his colour would change. One day some young men of his household passed by him (peace and blessings be upon him), and at this the colour of the Messenger of Allah (peace and blessings be upon him) changed. We said: O Messenger of Allah, we keep seeing something in you that is hard on us: the young men of your household pass by you and your colour changes because of it. He (peace and blessings be upon him) said: "Indeed, for these people of my household Allah has chosen the Hereafter, and He has not chosen this world for them."
