Muhammad or ʿAbdullah bin Abu Al-Mujalid said, "Abdullah bin Shaddad and Abu Burda differed regarding As-Salam, so they sent me to Ibn Abi ʿAufa and I asked him about it. He replied, 'In the lifetime of Messenger of Allah ﷺ, Abu Bakr and ʿUmar, we used to pay in advance the prices of wheat, barley, dried grapes and dates to be delivered later. I also asked Ibn Abza and he, too, replied as above.' "  

إِنَّا كُنَّا نُسْلِفُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ فِي الْحِنْطَةِ وَالشَّعِيرِ وَالزَّبِيبِ وَالتَّمْرِ وَسَأَلْتُ ابْنَ أَبْزَى فَقَالَ مِثْلَ ذَلِكَ  

'Abd Allah b. Shaddad and Abu Burdah disputed over salaf (payment in advance). They sent me to Ibn Abi Awfa and I asked him (about it) and he replied: We used to pay in advance (salaf) during the time of the Messenger of Allah ﷺ, Abu Bakr and 'Umar in wheat, barley, dates and raisins. Ibn Kathir added: "to those people who did not possess these things." The agreed version then goes: I then asked Ibn Abza who gave a similar reply.  

إِنْ كُنَّا نُسْلِفُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ فِي الْحِنْطَةِ وَالشَّعِيرِ وَالتَّمْرِ وَالزَّبِيبِ زَادَ ابْنُ كَثِيرٍ إِلَى قَوْمٍ مَا هُوَ عِنْدَهُمْ ثُمَّ اتَّفَقَا وَسَأَلْتُ ابْنَ أَبْزَى فَقَالَ مِثْلَ ذَلِكَ  

"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."  

كُنَّا نُسْلِمُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ وَعَهْدِ أَبِي بَكْرٍ وَعُمَرَ فِي الْحِنْطَةِ وَالشَّعِيرِ وَالزَّبِيبِ وَالتَّمْرِ عِنْدَ قَوْمٍ مَا عِنْدَهُمْ فَسَأَلْتُ ابْنَ أَبْزَى فَقَالَ مِثْلَ ذَلِكَ
