Narrated Abu Said:

Some people from the Ansar asked Allah's Apostle (to give them something) and he gave to everyone of them, who asked him, until all that he had was finished. When everything was finished and he had spent all that was in his hand, he said to them, '"(Know) that if I have any wealth, I will not withhold it from you (to keep for somebody else),
And (know) that he who refrains from begging others (or doing prohibited deeds), Allah will make him contented and not in need of others;
and he who remains patient, Allah will bestow patience upon him, and he who is satisfied with what he has, Allah will make him self-sufficient. And there is no gift better and vast (you may be given) than patience."

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي عَطَاءُ بْنُ يَزِيدَ، أَنَّ أَبَا سَعِيدٍ، أَخْبَرَهُ أَنَّ أُنَاسًا مِنَ الأَنْصَارِ سَأَلُوا رَسُولَ اللَّهِ ﷺ فَلَمْ يَسْأَلْهُ أَحَدٌ مِنْهُمْ إِلاَّ أَعْطَاهُ حَتَّى نَفِدَ مَا عِنْدَهُ فَقَالَ لَهُمْ حِينَ نَفِدَ كُلُّ شَىْءٍ أَنْفَقَ بِيَدَيْهِ " مَا يَكُنْ عِنْدِي مِنْ خَيْرٍ لاَ أَدَّخِرْهُ عَنْكُمْ، وَإِنَّهُ مَنْ يَسْتَعِفَّ يُعِفُّهُ اللَّهُ، وَمَنْ يَتَصَبَّرْ يُصَبِّرْهُ اللَّهُ، وَمَنْ يَسْتَغْنِ يُغْنِهِ اللَّهُ، وَلَنْ تُعْطَوْا عَطَاءً خَيْرًا وَأَوْسَعَ مِنَ الصَّبْرِ ".
