حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، عَنْ سُفْيَانَ، عَنْ أَبِي إِسْحَاقَ، عَنْ حَارِثَةَ، قَالَ جَاءَ نَاسٌ مِنْ أَهْلِ الشَّامِ إِلَى عُمَرَ رَضِيَ اللَّهُ عَنْهُ فَقَالُوا إِنَّا قَدْ أَصَبْنَا أَمْوَالًا وَخَيْلًا وَرَقِيقًا نُحِبُّ أَنْ يَكُونَ لَنَا فِيهَا زَكَاةٌ وَطَهُورٌ قَالَ مَا فَعَلَهُ صَاحِبَايَ قَبْلِي فَأَفْعَلَهُ وَاسْتَشَارَ أَصْحَابَ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَفِيهِمْ عَلِيٌّ رَضِيَ اللَّهُ عَنْهُ فَقَالَ عَلِيٌّ هُوَ حَسَنٌ إِنْ لَمْ يَكُنْ جِزْيَةً رَاتِبَةً يُؤْخَذُونَ بِهَا مِنْ بَعْدِكَ‏.‏

It was narrated from Abu Rafi’ that Umar bin al-Khattab was leaning on Ibn ‘Abbas, and Ibn 'Umar and Sa'eed bin Zaid were with him. He said

You should note that I have not said anything about kalalah and I have not appointed anyone to succeed me. Whoever of Arab captives are present when I die, are to be freed although they are among the wealth of Allah, may He be glorified and exalted. Sa'eed bin Zaid said: Why don't you suggest a man among the Muslims so that the people may follow your advice? Abu Bakr did that and the people followed his advice and trusted him. ‘Umar said: I have noticed too much greed and ambition, and I will leave this matter to be decided by these six people with whom the Messenger of Allah ﷺ was pleased when he died. Then ‘Umar said: If one of the two men were still alive, I would have referred to this matter to him and I would have trusted him: Salim the freed slave of Abu Hudhaifah and Abu 'Ubaidah bin al-Jarrah.
