Sunan Ibn Majah, Volume 5, Book 37, Hadith 4155 (DarusSalam) ⓘ
It was narrated that Abu Mas’ud said: “The Messenger of Allah used to enjoin charity, then one of us would go out and carry goods for others until he earned a Mudd, but one of them nowadays has one hundred thousand (Dinar or Dirham).” Shaqiq said: "It was as if he was hinting that this was he himself."
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ زَائِدَةَ، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ أَبِي مَسْعُودٍ، قَالَ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَأْمُرُ بِالصَّدَقَةِ فَيَنْطَلِقُ أَحَدُنَا يَتَحَامَلُ حَتَّى يَجِيءَ بِالْمُدِّ وَإِنَّ لأَحَدِهِمُ الْيَوْمَ مِائَةَ أَلْفٍ . قَالَ شَقِيقٌ كَأَنَّهُ يُعَرِّضُ بِنَفْسِهِ .
