TRUE PROSPERITY H 513 "Whosoever embraces Islam, and is given provision sufficient for his need, and is content with whatever Allah has given him has achieved true prosperity." R 513 Muslim with a chain up to Abdullah, the son of Amr son of Al 'As who related that the Messenger of Allah, praise and peace be upon him, said this.
511- وعن عبد الله بن عَمْرو بنِ العاص رضي الله عنهما : أن رسول الله صلى الله عليه وآله وسلم ، قَالَ : "قَدْ أفْلَحَ مَنْ أسْلَمَ ، وَكَانَ رِزْقُهُ كَفَافاً ، وَقَنَّعَهُ اللهُ بِمَا آتَاهُ" رواه مسلم .
