"When you come to a shepherd, call him three times. If he answers (all well and good), otherwise drink (milk from the flock) without taking advantage. And when you come to a garden call the owner of the garden three times. If he answers (all well and good), otherwise eat (from the produce of the garden) without taking advantage."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أَتَيْتَ عَلَى رَاعٍ فَنَادِهِ ثَلاَثَ مِرَارٍ فَإِنْ أَجَابَكَ وَإِلاَّ فَاشْرَبْ فِي غَيْرِ أَنْ تُفْسِدَ وَإِذَا أَتَيْتَ عَلَى حَائِطِ بُسْتَانٍ فَنَادِ صَاحِبَ الْبُسْتَانِ ثَلاَثَ مَرَّاتٍ فَإِنْ أَجَابَكَ وَإِلاَّ فَكُلْ فِي أَنْ لاَ تُفْسِدَ  

[Machine] Narrated by the Prophet ﷺ : "When you come upon a camel herder, call out 'O camel herder!' three times. If he responds, then ask him for milk from the camels without causing harm. But if he does not respond, then milk the camels and drink without causing harm. And when you come upon the owner of a garden wall, call out 'O owner of the garden wall!' three times. If he responds, then ask him for permission to eat from his garden. But if he does not respond, then eat without permission." The Messenger of Allah ﷺ also said, "Hospitality lasts for three days, any extra is charity."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أَتَيْتَ عَلَى رَاعِي إِبِلٍ فَنَادِ يَا رَاعِيَ الْإِبِلِ ثَلَاثًا فَإِنْ أَجَابَكَ وَإِلَّا فَاحْلُبْ وَاشْرَبْ مِنْ غَيْرِ أَنْ تُفْسِدَ وَإِذَا أَتَيْتَ عَلَى حَائِطِ بُسْتَانٍ فَنَادِ يَا صَاحِبَ الْحَائِطِ ثَلَاثًا فَإِنْ أَجَابَكَ وَإِلَّا فَكُلْ وَقَالَ رَسُولُ اللهِ ﷺ الضِّيَافَةُ ثَلَاثَةُ أَيَّامٍ فَمَا زَادَ فَصَدَقَةٌ  

"When you come to a shepherd, call him three times. If he answers (all well and good), otherwise drink (milk from the flock) without taking advantage. And when you come to a garden call the owner of the garden three times. If he answers (all well and good), otherwise eat (from the produce of the garden) without taking advantage." (Using translation from Ibn Mājah 2300)  

عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا أَتَيْتَ عَلَى رَاعٍ فَنَادِهِ ثَلَاثَ مَرَّاتٍ فَإِنْ أَجَابَكَ وَإِلَّا فَاشْرَبْ مِنْ غَيْرِ أَنْ تُفْسِدَ وَإِذَا أَتَيْتَ عَلَى حَائِطِ بُسْتَانٍ فَنَادِ صَاحِبَ الْبُسْتَانِ ثَلَاثَ مَرَّاتٍ فَإِنْ أَجَابَكَ وَإِلَّا فَكُلْ مِنْ غَيْرِ أَنْ تُفْسِدَ»  

"إذا أتيت على راعى إبلٍ فناد: يا راعى الإبل ثلاثًا، فإن أجابك وإلا فاحلبْ واشرب في غير أن تُفْسِدَ، وإذا أتيت على حائطٍ فناد: يا صاحب الحائط ثلاثًا، فإن أجابك وإلا فكل في غير أن تفسد" .
