'Abdullah bin 'Amr bin Al-as (May Allah be pleased with them) reported:
the Messenger of Allah (ﷺ) said, "Successful is the one who has entered the fold of Islam and is provided with sustenance which is sufficient for his needs, and Allah makes him content with what He has bestowed upon him.".

[Muslim].
