Sunan Ibn Majah, Volume 3, Book 12, Hadith 2146 (DarusSalam) ⓘ

It was narrated from Isma'il bin 'Ubaid bin Rifa'ah, from his father, that his grandfather Rifa'ah said: "We went out with the Messenger of Allah and the people were trading early in the morning. He called them: 'O merchants!' and when they looked up and craned their necks, he said : 'The merchants will be raised on the Day of Resurrection as immoral people, apart from those who fear Allah and act righteously and speak the truth (i.e. those who are honest)."'

حَدَّثَنَا يَعْقُوبُ بْنُ حُمَيْدِ بْنِ كَاسِبٍ، حَدَّثَنَا يَحْيَى بْنُ سُلَيْمٍ الطَّائِفِيُّ، عَنْ عَبْدِ اللَّهِ بْنِ عُثْمَانَ بْنِ خُثَيْمٍ، عَنْ إِسْمَاعِيلَ بْنِ عُبَيْدِ بْنِ رِفَاعَةَ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، رِفَاعَةَ قَالَ خَرَجْنَا مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَإِذَا النَّاسُ يَتَبَايَعُونَ بُكْرَةً فَنَادَاهُمْ ‏"‏ يَا مَعْشَرَ التُّجَّارِ ‏"‏ ‏.‏ فَلَمَّا رَفَعُوا أَبْصَارَهُمْ وَمَدُّوا أَعْنَاقَهُمْ قَالَ ‏"‏ إِنَّ التُّجَّارَ يُبْعَثُونَ يَوْمَ الْقِيَامَةِ فُجَّارًا إِلاَّ مَنِ اتَّقَى اللَّهَ وَبَرَّ وَصَدَقَ ‏"‏ ‏.‏
