[Machine] On the authority of the Prophet ﷺ, he said, "When one of you comes to a camel shepherd, let them call out 'O camel shepherd!' three times. If he responds, then good. If not, then let them milk and drink without burdening him. And when one of you comes to a wall, let them call out 'O people of the wall!' three times. If they respond, then good. If not, then let them eat without burdening them." The Messenger of Allah ﷺ also said, "Hospitality lasts for three days, and whatever exceeds that, it becomes charity."
عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا أَتَى أَحَدُكُمْ عَلَى رَاعِي إِبِلٍ فَلْيُنَادِي يَا رَاعِيَ الْإِبِلِ ثَلَاثًا فَإِنْ أَجَابَهُ وَإِلَّا فَلْيَحْلِبْ وَلْيَشْرَبْ وَلَا يَحْمِلَنَّ وَإِذَا أَتَى أَحَدُكُمْ عَلَى حَائِطٍ فَلْيُنَادِ ثَلَاثًا يَا أَصْحَابَ الْحَائِطِ فَإِنْ أَجَابَهُ وَإِلَّا فَلْيَأْكُلْ وَلَا يَحْمِلَنَّ» قَالَ وَقَالَ رَسُولُ اللَّهِ ﷺ «الضِّيَافَةُ ثَلَاثَةُ أَيَّامٍ فَمَا زَادَ فَصَدَقَةٌ»
