Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said, "He who believes in Allah and the Last Day, let him be hospitable to his guest; and he who believes in Allah and the Last Day, let him maintain good the ties of blood relationship; and he who believes in Allah and the Last Day, must speak good or remain silent".

[Al-Bukhari and Muslim].

وعنه أيضاً أن رسول الله قَالَ : « مَنْ كَانَ يُؤْمِنُ باللهِ وَاليَومِ الآخِرِ ، فَلْيُكْرِمْ ضَيْفَهُ ، وَمَنْ كَانَ يُؤْمِنُ باللهِ وَاليَومِ الآخِرِ ، فَلْيَصِلْ رَحِمَهُ ، وَمَنْ كَانَ يُؤْمِنُ بِاللهِ وَاليَومِ الآخِرِ ، فَلْيَقُلْ خَيْراً أَوْ لِيَصْمُتْ » . مُتَّفَقٌ عَلَيهِ .
