abudawud:2951 – Hārūn b. Zayd b. Abū al-Zarqāʾ from my father > Hishām b. Saʿd > Zayd b. Aslam

Zayd ibn Aslam said: Abdullah ibn Umar entered upon Mu'awiyah. He asked: (Tell me) your need, AbuAbdurRahman. He replied: Give (the spoils) to those who were set free, for I saw the first thing the Messenger of Allah ﷺ did when anything came to him was to give something to those who had been set free.  

أبو داود:٢٩٥١ – حَدَّثَنَا هَارُونُ بْنُ زَيْدِ بْنِ أَبِي الزَّرْقَاءِ حَدَّثَنَا أَبِي حَدَّثَنَا هِشَامُ بْنُ سَعْدٍ عَنْ زَيْدِ بْنِ أَسْلَمَ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ دَخَلَ عَلَى مُعَاوِيَةَ فَقَالَ حَاجَتُكَ يَا أَبَا عَبْدِ الرَّحْمَنِ فَقَالَ

عَطَاءُ الْمُحَرَّرِينَ فَإِنِّي رَأَيْتُ رَسُولَ اللَّهِ ﷺ أَوَّلَ مَا جَاءَهُ شَىْءٌ بَدَأَ بِالْمُحَرَّرِينَ

[Machine] I need the assistance of the Prophets' liberator; for I witnessed the Messenger of Allah ﷺ when something came to him that he did not start with any of them.  

البيهقي:١٢٩٩١ – وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ وَأَبُو طَاهِرٍ الْفَقِيهُ وَأَبُو زَكَرِيَّا بْنُ أَبِي إِسْحَاقَ وَأَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو قَالُوا ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ أنا مُحَمَّدُ بْنُ عَبْدِ اللهِ بْنِ عَبْدِ الْحَكَمِ أنا عَبْدُ اللهِ بْنُ نَافِعٍ ثنا هِشَامُ بْنُ سَعْدٍ عَنْ زَيْدِ بْنِ أَسْلَمَ عَنْ أَبِيهِ أَنَّ مُعَاوِيَةَ لَمَّا قَدِمَ الْمَدِينَةَ حَاجًّا جَاءَهُ عَبْدُ اللهِ بْنُ عُمَرَ فَقَالَ لَهُ مُعَاوِيَةُ حَاجَتُكَ يَا أَبَا عَبْدِ الرَّحْمَنِ؟ فَقَالَ

لَهُ حَاجَتِي عَطَاءُ الْمُحَرَّرِينَ؛ فَإِنِّي رَأَيْتُ رَسُولَ اللهِ ﷺ حِينَ جَاءَهُ شَيْءٌ لَمْ يَبْدَأْ بِأَوَّلَ مِنْهُمْ
