Sahih al-Bukhari 1479
Sahih al-Bukhari · Book 24: Obligatory Charity Tax (Zakat) · The Statement of Allah 'Azza wa Jall: "... They do not beg people persistently. ..." (2:273) And who may be considered to have enough to be content and abstain from begging"
Narrated Abu Huraira:
حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَبْدِ اللَّهِ ، قَالَ حَدَّثَنِي مَالِكٌ ، عَنْ أَبِي الزِّنَادِ ، عَنِ الأَعْرَجِ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لَيْسَ الْمِسْكِينُ الَّذِي يَطُوفُ عَلَى النَّاسِ تَرُدُّهُ اللُّقْمَةُ وَاللُّقْمَتَانِ وَالتَّمْرَةُ وَالتَّمْرَتَانِ، وَلَكِنِ الْمِسْكِينُ الَّذِي لاَ يَجِدُ غِنًى يُغْنِيهِ، وَلاَ يُفْطَنُ بِهِ فَيُتَصَدَّقُ عَلَيْهِ، وَلاَ يَقُومُ فَيَسْأَلُ النَّاسَ " .
Allah's Messenger (ﷺ) said, "The poor person is not the one who goes round the people and ask them for a mouthful or two (of meals) or a date or two but the poor is that who has not enough (money) to satisfy his needs and whose condition is not known to others, that others may give him something in charity, and who does not beg of people."
