عَن زهرَة بن معبد: أَنَّهُ كَانَ يَخْرُجُ بِهِ جَدُّهُ عَبْدُ اللَّهِ بْنُ هِشَامٍ إِلَى السُّوقِ فَيَشْتَرِيَ الطَّعَامَ فَيَلْقَاهُ ابْنُ عُمَرَ وَابْنُ الزُّبَيْرِ فَيَقُولَانِ لَهُ: أَشْرِكْنَا فَإِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَدْ دَعَا لَكَ بِالْبَرَكَةِ فَيُشْرِكُهُمْ فَرُبَّمَا أَصَابَ الرَّاحِلَةَ كَمَا هِيَ فَيَبْعَثُ بِهَا إِلَى الْمَنْزِلِ وَكَانَ عَبْدُ اللَّهِ بْنُ هِشَامٍ ذَهَبَتْ بِهِ أُمُّهُ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَمَسَحَ رَأسه ودعا لَهُ بِالْبركَةِ. رَوَاهُ البُخَارِيّ

Zuhra b. Ma’bad said his grandfather ‘Abdallah b. Hisham would take him out to the market and buy grain, and Ibn ‘Umar and Ibn az- Zubair would meet him and say to him, “Take us into partnership, for the Prophet has invoked a blessing on you then he would take them into partnership. He would often make a profit of a camel-load* and send it to the house. ‘Abdallah b. Hisham had been taken by his mother to the Prophet who passed his hand over his head and invoked a blessing on him. Bukhari transmitted it. * Another explanation is that this means he made enough profit to buy a camel with its load’ Cf. Mirqat , iii, 344.
