The Messenger of Allah, may Allah bless him and grant him peace, was reported to have said:--
''HE IS SUCCESSFUL WHO HAS ACCEPTED ISLAM, WHO HAS BEEN PROVIDED WITH
SUFFICIENT FOR HIS WANTS AND BEEN MADE CONTENTED BY ALLAH WITH WHAT
HE HAS GIVEN HIM''. [Muslim]
These days when people say so and so is very successful, what they mean is he is making a lot of money. By this noble Hadith, we understand who qualifies to be called successful. It is not having car x, house in y and a job z but:--- Islam, Needs fulfilled and Possession of a thankful heart. Note this accordingly.
