عَن المقدامِ بن معدي كرب سَمِعَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «أَيُّمَا مُسْلِمٍ ضَافَ قَوْمًا فَأَصْبَحَ الضَّيْفُ مَحْرُومًا كَانَ حَقًّا عَلَى كُلِّ مُسْلِمٍ نَصْرُهُ حَتَّى يَأْخُذَ لَهُ بِقِرَاهُ مِنْ مَالِهِ وَزَرْعِهِ» . رَوَاهُ الدَّارمِيّ وَأَبُو دَاوُد
وَفِي رِوَايَة: «وَأَيُّمَا رَجُلٍ ضَافَ قَوْمًا فَلَمْ يُقْرُوهُ كَانَ لَهُ أَن يعقبهم بِمثل قراه»
Translation
Abul Ahwas al-Jushami quoted his father to the effect that he said, "Messenger of God, tell me, if I come to a man who gives me no entertainment or hospitality and he afterwards comes to me, shall I give him entertainment or treat him as he treated me?" He replied, "No, give him entertainment." Tirmidhi transmitted it.
