Jami` at-Tirmidhi, Book 14, Hadith 59 (In-Book) ⓘ
Narrated 'Urwah Al-Bariqi: "The Messenger of Allah gave me on Dinar to purchase a sheep for him. So I purchased two sheeps for him, and I sold one of them for a Dinar. So I returned with the sheep and the Dinar to the Prophet, and I mentioned what had happened and he said: 'May Allah bless you in your business dealings.' After that we went to Kunasah in Al-Kufah, and he made tremendous profits. He was among the wealthiest of the people in Al-Kufah."
حَدَّثَنَا أَحْمَدُ بْنُ سَعِيدٍ الدَّارِمِيُّ، حَدَّثَنَا حَبَّانُ، وَهُوَ ابْنُ هِلاَلٍ أَبُو حَبِيبٍ الْبَصْرِيُّ حَدَّثَنَا هَارُونُ الأَعْوَرُ الْمُقْرِئُ، وَهُوَ ابْنُ مُوسَى الْقَارِئُ حَدَّثَنَا الزُّبَيْرُ بْنُ الْخِرِّيتِ، عَنْ أَبِي لَبِيدٍ، عَنْ عُرْوَةَ الْبَارِقِيِّ، قَالَ دَفَعَ إِلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم دِينَارًا لأَشْتَرِيَ لَهُ شَاةً فَاشْتَرَيْتُ لَهُ شَاتَيْنِ فَبِعْتُ إِحْدَاهُمَا بِدِينَارٍ وَجِئْتُ بِالشَّاةِ وَالدِّينَارِ إِلَى النَّبِيِّ صلى الله عليه وسلم . فَذَكَرَ لَهُ مَا كَانَ مِنْ أَمْرِهِ فَقَالَ لَهُ " بَارَكَ اللَّهُ لَكَ فِي صَفْقَةِ يَمِينِكَ " . فَكَانَ يَخْرُجُ بَعْدَ ذَلِكَ إِلَى كُنَاسَةِ الْكُوفَةِ فَيَرْبَحُ الرِّبْحَ الْعَظِيمَ فَكَانَ مِنْ أَكْثَرِ أَهْلِ الْكُوفَةِ مَالاً .
