عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ ((أَيُّمَا ضَيْفٍ نَزَلَ بِقَوْمٍ فَأَصْبَحَ الضَّيْفُ مَحْرُومًا فَلَهُ أَنْ يَأْخُذَ بِقَدْرِ قِرَاهُ وَلَا حَرَجَ عَلَيْهِ))
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: If a guest stays with some people, but in the morning he finds himself deprived of his right, then it will be permissible for him to take from them according to the measure of his hospitality; there will be no blame upon him in this.
