Sahih al-Bukhari 2461
Narrated `Uqba bin 'Amir:
We said to the Prophet, "You send us out and it happens that we have to stay with people who do not entertain us. What do you think about it? He said to us, "If you stay with some people and they entertain you as they should for a guest, accept their hospitality, but if they don't, take the right of 
the guest from them."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا اللَّيْثُ، قَالَ حَدَّثَنِي يَزِيدُ، عَنْ أَبِي الْخَيْرِ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، قَالَ قُلْنَا لِلنَّبِيِّ صلى الله عليه وسلم إِنَّكَ تَبْعَثُنَا فَنَنْزِلُ بِقَوْمٍ لاَ يَقْرُونَا فَمَا تَرَى فِيهِ فَقَالَ لَنَا ‏
"‏ إِنْ نَزَلْتُمْ بِقَوْمٍ، فَأُمِرَ لَكُمْ بِمَا يَنْبَغِي لِلضَّيْفِ فَاقْبَلُوا، فَإِنْ لَمْ يَفْعَلُوا فَخُذُوا مِنْهُمْ حَقَّ الضَّيْفِ ‏"‏‏.‏
