مُسْنَدُ أَحْمَدَ
Musnad Ahmad 218
Musnad `Umar b. al-Khattab (ra)
قَالَ قَرَأْتُ عَلَى يَحْيَى بْنِ سَعِيدٍ عَنْ زُهَيْرٍ، قَالَ حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ حَارِثَةَ بْنِ مُضَرِّبٍ، أَنَّهُ حَجَّ مَعَ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ فَأَتَاهُ أَشْرَافُ أَهْلِ الشَّامِ فَقَالُوا يَا أَمِيرَ الْمُؤْمِنِينَ إِنَّا أَصَبْنَا مِنْ أَمْوَالِنَا رَقِيقًا وَدَوَابَّ فَخُذْ مِنْ أَمْوَالِنَا صَدَقَةً تُطَهِّرُنَا بِهَا وَتَكُونُ لَنَا زَكَاةً فَقَالَ هَذَا شَيْءٌ لَمْ يَفْعَلْهُ اللَّذَانِ كَانَا مِنْ قَبْلِي وَلَكِنْ انْتَظِرُوا حَتَّى أَسْأَلَ الْمُسْلِمِينَ.
It was narrated from Harithah bin Mudarrib that he did Hajj with ‘Umar bin al Khattab (رضي الله عنه). The nobles of Syria came to him ['Umar) and said: O Ameer al-Mu'mineen, we have acquired slaves and mounts, so take charity from our wealth in order to purify us thereby, and it will be zakah for us. He said: This is something that the two who came before me did not do; I shall wait until I ask the Muslims.
