Sahih+3

It was narrated that ‘Abdullah bin ‘Amr said:“A man came to the Messenger of Allah (ﷺ) and said: ‘O Messenger of Allah, I have come seeking to go out in Jihad with you, seeking thereby the Face of Allah and the Hereafter. I have come even though my parents are weeping.’ He said: ‘Go back to them and make them smile as you have made them weep.’”
