Sunan an-Nasa'i, Volume 3, Book 23, Hadith 2596 (DarusSalam) ⓘ

It was narrated from 'Abdur-Rahman bin Abu Sa'eed Al-Khudri that his father said: "My mother sent me to the Messenger of Allah, and I came to him and sat down. He turned to me and said: 'Whoever wants to be independent of means, Allah, the Mighty and Sublime, will make him independent. Whoever wants to refrain from asking, Allah, the Mighty and Sublime, will help him to refrain. Whoever wants to be content with his lot, Allah, the Mighty and Sublime, Allah, the Mighty and Sublime, will suffice him. Whoever asks when he has something worth one Uqiyah, then he is being too demanding. 'I said: 'My she-camel Al-Yaqutah is worth more than and Uqiyah,' so I came back and did not ask him for anything."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا ابْنُ أَبِي الرِّجَالِ، عَنْ عُمَارَةَ بْنِ غَزِيَّةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنْ أَبِيهِ، قَالَ سَرَّحَتْنِي أُمِّي إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَأَتَيْتُهُ وَقَعَدْتُ فَاسْتَقْبَلَنِي وَقَالَ ‏ "‏ مَنِ اسْتَغْنَى أَغْنَاهُ اللَّهُ عَزَّ وَجَلَّ وَمَنِ اسْتَعَفَّ أَعَفَّهُ اللَّهُ عَزَّ وَجَلَّ وَمَنِ اسْتَكْفَى كَفَاهُ اللَّهُ عَزَّ وَجَلَّ وَمَنْ سَأَلَ وَلَهُ قِيمَةُ أُوقِيَّةٍ فَقَدْ أَلْحَفَ ‏" ‏ ‏.‏ فَقُلْتُ نَاقَتِي الْيَاقُوتَةُ خَيْرٌ مِنْ أُوقِيَّةٍ فَرَجَعْتُ وَلَمْ أَسْأَلْهُ ‏.‏
