Umar bin al-Khattaab relates that:

'I heard the Messenger of Allaah, sallallaahu alayhi wa sallam, saying,
"verily actions are by intentions, and for every person is what he intended. So the one whose hijra was to Allaah and His Messenger, then his hijrah was to Allaah and His Messenger. And the one whose hijrah was for the world to gain from it, or a woman to marry her, then his hijrah was to what he made hijrah for."
