Yahya related to me from Malik from Ibn Shihab that as-Sa'ib ibn Yazid said, "As a young man I used to work with Abdullah ibn Utba ibn Masud in the market of Madina in the time of Umar ibn al-Khattab and we used to take a tenth from the Nabateans."
أَنَّهُ قَالَ كُنْتُ غُلاَمًا عَامِلاً مَعَ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ عَلَى سُوقِ الْمَدِينَةِ فِي زَمَانِ عُمَرَ بْنِ الْخَطَّابِ فَكُنَّا نَأْخُذُ مِنَ النَّبَطِ الْعُشْرَ
