It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he said: "A young man came to the Prophet (peace and blessings be upon him) and said: 'I intend to go in this direction, that is, for Hajj.' The narrator said: So the Messenger of Allah (peace and blessings be upon him) walked with him (to see him off) and said: 'O young man! Zawwadaka Allahu al-taqwa, wa wajjahaka al-khayr, wa kafaka al-hamm (May Allah provide you with piety as your provision, turn you towards good, and suffice you against your worries).' Then, when the young man returned, he greeted the Prophet (peace and blessings be upon him) with salam. He (peace and blessings be upon him) raised his blessed head towards him and said: 'O young man! Qabila Allahu hajjaka, wa kaffara dhanbaka, wa akhlafa nafaqataka (May Allah accept your Hajj, expiate your sin, and replace what you spent).'"
This is how it appears in the Dar al-Haramayn edition, whereas the correct name is al-Hasan bin Yahya al-Ruzzi (may Allah have mercy on him).
