Sunan Ibn Majah, Book 15, Hadith 2493 (In-Book) ⓘ
It was narrated from 'Urwah Al-Bariqi that : the Prophet gave him a Dinar to buy him a sheep, and he bought two sheep for him, then he sold one of them for a Dinar, and bought a Dinar and a sheep to the Prophet. The Messenger of Allah prayed for blessing for him.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ شَبِيبِ بْنِ غَرْقَدَةَ، عَنْ عُرْوَةَ الْبَارِقِيِّ، أَنَّ النَّبِيَّ صلى الله عليه وسلم أَعْطَاهُ دِينَارًا يَشْتَرِي لَهُ شَاةً فَاشْتَرَى لَهُ شَاتَيْنِ فَبَاعَ إِحْدَاهُمَا بِدِينَارٍ فَأَتَى النَّبِيَّ صلى الله عليه وسلم بِدِينَارٍ وَشَاةٍ فَدَعَا لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم بِالْبَرَكَةِ . قَالَ فَكَانَ لَوِ اشْتَرَى التُّرَابَ لَرَبِحَ فِيهِ .
