باب الْمِسْكِينِ الَّذِي لاَ يَجِدُ غِنًى وَلاَ يُفْطَنُ لَهُ فَيُتَصَدَّقَ عَلَيْهِ ‏
Sahih Muslim 1039 b

Abu Huraira reported Allah's Messenger (ﷺ) as saying:

Miskin is not he who is dismissed with one or two dates, and with one morsel or two morsels. (In fact) miskin is he who abstains (from begging). Read if you so desire (the verse):" They beg not of men importunately)" (ii. 273).
حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ ابْنُ أَيُّوبَ حَدَّثَنَا إِسْمَاعِيلُ، - وَهُوَ ابْنُ جَعْفَرٍ - أَخْبَرَنِي شَرِيكٌ، عَنْ عَطَاءِ بْنِ يَسَارٍ، مَوْلَى مَيْمُونَةَ عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لَيْسَ الْمِسْكِينُ بِالَّذِي تَرُدُّهُ التَّمْرَةُ وَالتَّمْرَتَانِ وَلاَ اللُّقْمَةُ وَاللُّقْمَتَانِ إِنَّمَا الْمِسْكِينُ الْمُتَعَفِّفُ اقْرَءُوا إِنْ شِئْتُمْ ‏{‏ لاَ يَسْأَلُونَ النَّاسَ إِلْحَافًا‏}‏ ‏"‏ ‏.‏
