It was narrated that Abu Mas'ud said:"The Messenger of Allah used to tell us to give in charity, and one of us could not find anything to give until he went to the market place and hired himself out to carry loads for people. Then he would bring a Mudd and give it to the Messenger of Allah. I know a man who has a hundred thousand now, but on that day he had (only) one Dirham."
أَخْبَرَنَا الْحُسَيْنُ بْنُ حُرَيْثٍ، قَالَ أَنْبَأَنَا الْفَضْلُ بْنُ مُوسَى، عَنِ الْحُسَيْنِ، عَنْ مَنْصُورٍ، عَنْ شَقِيقٍ، عَنْ أَبِي مَسْعُودٍ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَأْمُرُنَا بِالصَّدَقَةِ فَمَا يَجِدُ أَحَدُنَا شَيْئًا يَتَصَدَّقُ بِهِ حَتَّى يَنْطَلِقَ إِلَى السُّوقِ فَيَحْمِلَ عَلَى ظَهْرِهِ فَيَجِيءَ بِالْمُدِّ فَيُعْطِيَهُ رَسُولَ اللَّهِ صلى الله عليه وسلم إِنِّي لأَعْرِفُ الْيَوْمَ رَجُلاً لَهُ مِائَةُ أَلْفٍ مَا كَانَ لَهُ يَوْمَئِذٍ دِرْهَمٌ .
