Sunan Abi Dawud, Hadith 3459 ⓘ

Narrated Abdullah ibn AbuAwfa ibn AbuAwfa al-Aslami: We made a journey to Syria on an expedition along with the Messenger of Allah. The Nabateans of Syria came to us and we paid in advance to them (in a salam contract) in wheat and olive oil at a specified rate and for a specified time. He asked (by the people): you might have contracted with him who had these things in his possession? He replied: We did not ask them.

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُصَفَّى، حَدَّثَنَا أَبُو الْمُغِيرَةِ، حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ أَبِي غَنِيَّةَ، حَدَّثَنِي أَبُو إِسْحَاقَ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى الأَسْلَمِيِّ، قَالَ غَزَوْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم الشَّامَ فَكَانَ يَأْتِينَا أَنْبَاطٌ مِنْ أَنْبَاطِ الشَّامِ فَنُسْلِفُهُمْ فِي الْبُرِّ وَالزَّيْتِ سِعْرًا مَعْلُومًا وَأَجَلاً مَعْلُومًا فَقِيلَ لَهُ مِمَّنْ لَهُ ذَلِكَ قَالَ مَا كُنَّا نَسْأَلُهُمْ ‏.‏
