The Messenger of Allah, Prophet Muhammad, 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 tone called successful. It is not having car x, house in y and a job z but:-- Islam, Needs fulfilled and a thankful heart. Note this accordingly.
