عَنْ عَلْقَمَةَ بْنِ عَبْدِ اللَّهِ الْمُزَنِيِّ رَضِيَ اللَّهُ عَنْهُ عَنْ رِجَالٍ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيَتَّقِ اللَّهَ عَزَّ وَجَلَّ وَلْيُكْرِمْ جَارَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيَتَّقِ اللَّهَ وَلْيُكْرِمْ ضَيْفَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيَتَّقِ اللَّهَ وَلْيَقُلْ حَقًّا أَوْ لِيَسْكُتْ
Some of the Companions narrate that the Messenger of Allah, peace and blessings be upon him, said: Whoever believes in Allah and the Last Day should honor his neighbor; whoever believes in Allah and the Last Day should fear Allah and honor his guest; and whoever believes in Allah and the Last Day should fear Allah and speak good or remain silent.
