Hadith: Successful is the one who enters Islam and is provided with mere subsistence and Allah makes him content with what He has given him

عن عبدالله بن عمرو بن العاص- رضي الله عنه- أن رسول الله صلى الله عليه وسلم قال: «قد أفلح من أسلم وكان رزقُهُ كَفَافًا وقَنَّعَهُ الله بما آتاه». وعن أبي محمد فضالة بن عبيد الأنصاري رضي الله عنه : أنه سمع رسول الله صلى الله عليه وسلم يقول: «طُوبَى لمن هُدِيَ للإسلام، وكان عَيْشُهُ كَفَافًا وقَنِعَ».
[صحيحان] - [حديث ابن عمرو رضي الله عنهما: رواه مسلم. حديث فضالة بن عبيد رضي الله عنه: رواه الترمذي وأحمد]

‘Abdullāh ibn ‘Amr ibn al-‘Ās (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Successful is the one who enters Islam and is provided with mere subsistence and Allah makes him content with what He has given him." Abu Muhammad Fadalah ibn ‘Ubayd al-Ansāri (may Allah be pleased with him) reported that he heard the Messenger (may Allah's peace and blessings be upon him) say: "Blissful is the one who is guided to Islam and possesses mere subsistence and shows contentment."
[Sahih/Authentic with its two versions] - [Narrated by At-Termedhy - Narrated by Ahmad - Narrated by Muslim]

Explanation

Tūba, a tree in Paradise, is glad tidings for one who has been guided to Islam and his provisions are barely sufficient for him, not less to keep him distracted or more to make him transgress. It is a complete favor by Allah, the Almighty, when He endows us with sustenance that both suffices us and prevents us from transgression.
