From Hakim bin Hizam, that the Messenger of Allah ﷺ sent Hakim bin Hizam with a Dinar to buy an animal for Udhiyyah (an animal for sacrifice) for him. He purchases an Udhiyyah which he sold and profited a Dinar from, so he purchased another in its place. And he returned to the Messenger of Allah ﷺ with Udhiyyah and the Dinar, so he said: 'The sheep is for sacrifice and Dinar is for charity.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ حَكِيمَ بْنَ حِزَامٍ يَشْتَرِي لَهُ أُضْحِيَّةً بِدِينَارٍ فَاشْتَرَى أُضْحِيَّةً فَأُرْبِحَ فِيهَا دِينَارًا فَاشْتَرَى أُخْرَى مَكَانَهَا فَجَاءَ بِالأُضْحِيَّةِ وَالدِّينَارِ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ ضَحِّ بِالشَّاةِ وَتَصَدَّقْ بِالدِّينَارِ  

"The Messenger of Allah ﷺ 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 ﷺ, 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."  

دَفَعَ إِلَىَّ رَسُولُ اللَّهِ ﷺ دِينَارًا لأَشْتَرِيَ لَهُ شَاةً فَاشْتَرَيْتُ لَهُ شَاتَيْنِ فَبِعْتُ إِحْدَاهُمَا بِدِينَارٍ وَجِئْتُ بِالشَّاةِ وَالدِّينَارِ إِلَى النَّبِيِّ ﷺ 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
