Musnad Ahmad 17
It was narrated from Awsat bin Isma'eel al-Bajali that he heard Abu Bakr, when the Prophet (ﷺ) had passed away, saying:
The Messenger of Allah (ﷺ) stood last year in this place where I am standing. Then Abu Bakr wept, then he said: “You must adhere to the truth, for with it comes righteousness and they both lead to Paradise. And you must beware of lying for with it comes immorality and they both lead to Hell. Ask Allah to keep you safe and sound, for no one is given anything, after certain faith (yaqeen) that is better than being kept safe and sound.` Then he said: “Do not sever ties with one another, do not turn your backs on one another, do not bear grudges against one another, do not envy one another, and be, O slaves of Allah, brothers.`
حَدَّثَنَا هَاشِمٌ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي يَزِيدُ بْنُ خُمَيْرٍ، قَالَ سَمِعْتُ سُلَيْمَ بْنَ عَامِرٍ، رَجُلًا مِنْ حِمْيَرَ يُحَدِّثُ عَنْ أَوْسَطَ بْنِ إِسْمَاعِيلَ بْنِ أَوْسَطَ الْبَجَلِيِّ، يُحَدِّثُ عَنْ أَبِي بَكْرٍ، أَنَّهُ سَمِعَهُ حِينَ، تُوُفِّيَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ قَامَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَامَ الْأَوَّلِ مَقَامِي هَذَا ثُمَّ بَكَى ثُمَّ قَالَ عَلَيْكُمْ بِالصِّدْقِ فَإِنَّهُ مَعَ الْبِرِّ وَهُمَا فِي الْجَنَّةِ وَإِيَّاكُمْ وَالْكَذِبَ فَإِنَّهُ مَعَ الْفُجُورِ وَهُمَا فِي النَّارِ وَسَلُوا اللَّهَ الْمُعَافَاةَ فَإِنَّهُ لَمْ يُؤْتَ رَجُلٌ بَعْدَ الْيَقِينِ شَيْئًا خَيْرًا مِنْ الْمُعَافَاةِ ثُمَّ قَالَ لَا تَقَاطَعُوا وَلَا تَدَابَرُوا وَلَا تَبَاغَضُوا وَلَا تَحَاسَدُوا وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا‏.‏
