حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَحْمَدَ بْنِ بَشِيرِ بْنِ ذَكْوَانَ، وَمَحْمُودُ بْنُ خَالِدٍ الدِّمَشْقِيَّانِ، - الْمَعْنَى - قَالاَ حَدَّثَنَا مَرْوَانُ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنَا يَحْيَى بْنُ حَمْزَةَ، قَالَ سَمِعْتُ أَبَا وَهْبٍ، يَقُولُ سَمِعْتُ مَكْحُولاً، يَقُولُ كُنْتُ عَبْدًا بِمِصْرَ لاِمْرَأَةٍ مِنْ بَنِي هُذَيْلٍ فَأَعْتَقَتْنِي فَمَا خَرَجْتُ مِنْ مِصْرَ وَبِهَا عِلْمٌ إِلاَّ حَوَيْتُ عَلَيْهِ فِيمَا أُرَى ثُمَّ أَتَيْتُ الْحِجَازَ فَمَا خَرَجْتُ مِنْهَا وَبِهَا عِلْمٌ إِلاَّ حَوَيْتُ عَلَيْهِ فِيمَا أُرَى ثُمَّ أَتَيْتُ الْعِرَاقَ فَمَا خَرَجْتُ مِنْهَا وَبِهَا عِلْمٌ إِلاَّ حَوَيْتُ عَلَيْهِ فِيمَا أُرَى ثُمَّ أَتَيْتُ الشَّامَ فَغَرْبَلْتُهَا كُلُّ ذَلِكَ أَسْأَلُ عَنِ النَّفْلِ فَلَمْ أَجِدْ أَحَدًا يُخْبِرُنِي فِيهِ بِشَىْءٍ حَتَّى أَتَيْتُ شَيْخًا يُقَالُ لَهُ زِيَادُ بْنُ جَارِيَةَ التَّمِيمِيُّ فَقُلْتُ لَهُ هَلْ سَمِعْتَ فِي النَّفْلِ شَيْئًا قَالَ نَعَمْ سَمِعْتُ حَبِيبَ بْنَ مَسْلَمَةَ الْفِهْرِيَّ يَقُولُ شَهِدْتُ النَّبِيَّ صلى الله عليه وسلمنَفَّلَ الرُّبُعَ فِي الْبَدْأَةِ وَالثُّلُثَ فِي الرَّجْعَةِ ‏.‏
Translation
Narrated Habib ibn Maslamah al-Fihri

Makhul said: I was a slave in Egypt belonging to a woman of Banu Hudhayl, and she emancipated me. I did not leave Egypt while there was any knowledge in it that I had not acquired, as I suppose. Then I came to the Hijaz, and I did not leave it while there was any knowledge in it that I had not acquired, as I suppose. Then I came to Iraq, and I did not leave it while there was any knowledge in it that I had not acquired, as I suppose. Then I came to al-Sham and searched through it, asking about the voluntary gift (nafl), but I did not find anyone who could tell me anything about it until I came to an old man called Ziyad ibn Jariyah al-Tamimi. I said to him: Did you hear anything regarding the voluntary gift (nafl)? He said: Yes, I heard Habib ibn Maslamah al-Fihri saying: I witnessed the Prophet (ﷺ) award a fourth of the spoils as a voluntary gift at the outset, and a third upon the return.
