'Asim bin 'Ubaidullah said: ' I heard Salim bin 'Abdullah narrating a Hadith from his father who said: "'Umar said : "O Messenger of Allah! Do you see that what we do is a new matter- or a matter initiated – or it is a matter already concluded?” He (s.a.w) said: “ O Ibn Al-Khattab! It is a matter already concluded. For everyone is suited (for that for which he is created). As for one who is among the people of happiness, then he works for happiness, and as for the one who is among the people of misery, then he works for his misery.” (Hasan)
