Sahih al-Bukhari 6353
Narrated Abu `Aqil:
that his grandfather. `Abdullah bin Hisham used to take him from the market or to the market (the 
narrator is in doubt) and used to buy grain and when Ibn Az-Zubair and Ibn `Umar met him, they 
would say to him, "Let us be your partners (in trading) as the Prophet (ﷺ) invoked for Allah's blessing 
upon you." He would then take them as partners and he would Sometimes gain a whole load carried 
by an animal which he would send home.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا ابْنُ وَهْبٍ، حَدَّثَنَا سَعِيدُ بْنُ أَبِي أَيُّوبَ، عَنْ أَبِي عَقِيلٍ، أَنَّهُ كَانَ يَخْرُجُ بِهِ جَدُّهُ عَبْدُ اللَّهِ بْنُ هِشَامٍ مِنَ السُّوقِ أَوْ إِلَى السُّوقِ فَيَشْتَرِي الطَّعَامَ، فَيَلْقَاهُ ابْنُ الزُّبَيْرِ وَابْنُ عُمَرَ فَيَقُولاَنِ أَشْرِكْنَا فَإِنَّ النَّبِيَّ صلى الله عليه وسلم قَدْ دَعَا لَكَ بِالْبَرَكَةِ‏.‏ فَرُبَّمَا أَصَابَ الرَّاحِلَةَ كَمَا هِيَ، فَيَبْعَثُ بِهَا إِلَى الْمَنْزِلِ‏.‏
