That the Prophet ﷺ said: "Whoever enters an orchard then let him eat, but not take any in his garment." [He said:] There are narrations on this topic from 'Abdullah bin 'Amr, 'Abbad bin Shurahbil, Rafi' bin 'Amr, 'Umair the freed slave of Abi Al-Lahm, and Abu Hurairah.  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ دَخَلَ حَائِطًا فَلْيَأْكُلْ وَلاَ يَتَّخِذْ خُبْنَةً قَالَ وَفِي الْبَابِ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو وَعَبَّادِ بْنِ شُرَحْبِيلَ وَرَافِعِ بْنِ عَمْرٍو وَعُمَيْرٍ مَوْلَى آبِي اللَّحْمِ وَأَبِي هُرَيْرَةَ  

"I was throwing stones at a date-palm belonging to some of the Ansar. They took me along with them to the Prophet ﷺ. He said: "O Rafi'! Why were you throwing stones at their date-palm?'" He said: "I said: 'Out of hunger, O Messenger of Allah! He said: 'Do not throw stones at them, eat what falls. May Allah fill you and quench your thirst.'" This Hadith is Hasan Gharib Sahih.  

كُنْتُ أَرْمِي نَخْلَ الأَنْصَارِ فَأَخَذُونِي فَذَهَبُوا بِي إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَافِعُ لِمَ تَرْمِي نَخْلَهُمْ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ الْجُوعُ قَالَ لاَ تَرْمِ وَكُلْ مَا وَقَعَ أَشْبَعَكَ اللَّهُ وَأَرْوَاكَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ  

From his father, from his grandfather, that the Prophet ﷺ was asked about hanging fruits (on the trees), so he said: "Whoever is in need and picks some of it without taking any in his garment, then there is no sin upon him."  

أَنَّ النَّبِيَّ ﷺ سُئِلَ عَنِ الثَّمَرِ الْمُعَلَّقِ فَقَالَ مَنْ أَصَابَ مِنْهُ مِنْ ذِي حَاجَةٍ غَيْرَ مُتَّخِذٍ خُبْنَةً فَلاَ شَىْءَ عَلَيْهِ
