It was narrated that Jabir bin Samurah said:
'Umar bin Khattab addressed us at Jabiyah and said: “The Messenger of Allah ﷺ stood up among us as I stand among you, and said: 'Honor my Companions for my sake, then those who come after them, then those who come after them. Then lying will prevail until a man will give testimony without being asked to do so, and he will swear an oath without being asked to do so.' ”

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْجَرَّاحِ، حَدَّثَنَا جَرِيرٌ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ خَطَبَنَا عُمَرُ بْنُ الْخَطَّابِ بِالْجَابِيَةِ فَقَالَ إِنَّ رَسُولَ اللَّهِ ﷺ قَامَ فِينَا مِثْلَ مُقَامِي فِيكُمْ فَقَالَ " احْفَظُونِي فِي أَصْحَابِي ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ الَّذِينَ يَلُونَهُمْ ثُمَّ يَفْشُو الْكَذِبُ حَتَّى يَشْهَدَ الرَّجُلُ وَمَا يُسْتَشْهَدُ وَيَحْلِفَ وَمَا يُسْتَحْلَفُ " .
