Regarding Musaqah

Narrated Ibn 'Umar:
The Messenger of Allah ﷺ made an agreement with the people of Khaibar to work and cultivate in return for half of the fruits or produce.

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ ﷺ عَامَلَ أَهْلَ خَيْبَرَ بِشَطْرِ مَا يَخْرُجُ مِنْ ثَمَرٍ أَوْ زَرْعٍ .

Narrated Ibn 'Umar:
The Prophet ﷺ handed over the Jews of Khaibar the palm trees and the land of Khaibar on condition that they should employ what belonged to them in working on them, and that he should have half of the fruits.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنِ اللَّيْثِ، عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ، - يَعْنِي ابْنَ غَنَجٍ - عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ ﷺ دَفَعَ إِلَى يَهُودِ خَيْبَرَ نَخْلَ خَيْبَرَ وَأَرْضَهَا عَلَى أَنْ يَعْتَمِلُوهَا مِنْ أَمْوَالِهِمْ وَأَنَّ لِرَسُولِ اللَّهِ ﷺ شَطْرَ ثَمَرَتِهَا .

Narrated Ibn 'Abbas:
The Messenger of Allah ﷺ conquered Khaibar, and stipulated that all the land, gold and silver would belong to him. The people of Khaibar said: we know the land more than you ; so give it to us on condition that you should have half of the produce and we would have the half. He then gave it to them on that condition. When the time of picking the fruits of the palm-trees came, he sent 'Abd Allah b. Rawahah to them, and he assessed the among of the fruits of the palm-trees. This is what the people of Medina call khars (assessment). He used to say: In these palm-trees there is such-and-such amount (of produce). They would say: You assessed more to us, Ibn Rawahah (than the real amount). He would say: I first take the responsibility of assessing the fruits of the palm-trees and give you half of (the amount) I said. They would say: This is true, and on this (equity) stand the heavens and the earth. We agreed that we should take (the amount which) you said.

حَدَّثَنَا أَيُّوبُ بْنُ مُحَمَّدٍ الرَّقِّيُّ، حَدَّثَنَا عُمَرُ بْنُ أَيُّوبَ، حَدَّثَنَا جَعْفَرُ بْنُ بُرْقَانَ، عَنْ مَيْمُونِ بْنِ مِهْرَانَ، عَنْ مِقْسَمٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ افْتَتَحَ رَسُولُ اللَّهِ ﷺ خَيْبَرَ وَاشْتَرَطَ أَنَّ لَهُ الأَرْضَ وَكُلَّ صَفْرَاءَ وَبَيْضَاءَ . قَالَ أَهْلُ خَيْبَرَ نَحْنُ أَعْلَمُ بِالأَرْضِ مِنْكُمْ فَأَعْطِنَاهَا عَلَى أَنَّ لَكُمْ نِصْفَ الثَّمَرَةِ وَلَنَا نِصْفٌ . فَزَعَمَ أَنَّهُ أَعْطَاهُمْ عَلَى ذَلِكَ فَلَمَّا كَانَ حِينَ يُصْرَمُ النَّخْلُ بَعَثَ إِلَيْهِمْ عَبْدَ اللَّهِ بْنَ رَوَاحَةَ فَحَزَرَ عَلَيْهِمُ النَّخْلَ وَهُوَ الَّذِي يُسَمِّيهِ أَهْلُ الْمَدِينَةِ الْخَرْصَ فَقَالَ فِي ذِهْ كَذَا وَكَذَا قَالُوا أَكْثَرْتَ عَلَيْنَا يَا ابْنَ رَوَاحَةَ . فَقَالَ فَأَنَا أَلِي حَزْرَ النَّخْلِ وَأُعْطِيكُمْ نِصْفَ الَّذِي قُلْتُ . قَالُوا هَذَا الْحَقُّ وَبِهِ تَقُومُ السَّمَاءُ وَالأَرْضُ قَدْ رَضِينَا أَنْ نَأْخُذَهُ بِالَّذِي قُلْتَ .

The tradition mentioned above has also been narrated by Ja'far b. Burqan through his chain and to the same effect. This version has:
He said: He assessed, and after the words of kull safara' wa baida', he said: that is, gold and silver will belong to him.

حَدَّثَنَا مُحَمَّدُ بْنُ سَهْلٍ الرَّمْلِيُّ، حَدَّثَنَا زَيْدُ بْنُ أَبِي الزَّرْقَاءِ، عَنْ جَعْفَرِ بْنِ بُرْقَانَ، بِإِسْنَادِهِ وَمَعْنَاهُ قَالَ فَحَزَرَ وَقَالَ عِنْدَ قَوْلِهِ وَكُلَّ صَفْرَاءَ وَبَيْضَاءَ يَعْنِي الذَّهَبَ وَالْفِضَّةَ لَهُ .
