Salaam everyone,
The Messenger of Allah, Sayyidina Muhammad Sallallahu alaihi Wasallama, 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/she 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, Fulfilled needs and Possession of a thankful heart. Note this well.

Many Regards.
