It was narrated that Abu Mujalid said:
"Abdullah bin Shaddad and Abu Barzah had a dispute about paying in advance. They sent me to 'Abdullah bin Abu Awfa to ask him about it. He said: 'We used to make payments in advance at the time of the Messenger of Allah ﷺ and the time of Abu Bakr and 'Umar, for wheat, barley, raisins and dates, to people who did not yet possess those things.' I asked Ibn Abza, and he said something similar."

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، وَعَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، قَالاَ حَدَّثَنَا شُعْبَةُ، - قَالَ يَحْيَى عَنْ عَبْدِ اللَّهِ بْنِ أَبِي الْمُجَالِدِ، وَقَالَ عَبْدُ الرَّحْمَنِ، عَنِ ابْنِ أَبِي الْمُجَالِدِ، - قَالَ امْتَرَى عَبْدُ اللَّهِ بْنُ شَدَّادٍ وَأَبُو بُرْدَةَ فِي السَّلَمِ فَأَرْسَلُونِي إِلَى عَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى فَسَأَلْتُهُ فَقَالَ كُنَّا نُسْلِمُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ وَعَهْدِ أَبِي بَكْرٍ وَعُمَرَ فِي الْحِنْطَةِ وَالشَّعِيرِ وَالزَّبِيبِ وَالتَّمْرِ عِنْدَ قَوْمٍ مَا عِنْدَهُمْ .
