Narrated ' Abdullah bin 'Abbas:

That Abu Sufyan bin Harb Informed him that Heraclius called him and the members of a caravan from Quraish who had gone to Sham as traders, during the truce which Allah's Apostle had concluded with Abu Sufyan and the Quraish infidels.

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، أَخْبَرَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ أَخْبَرَهُ أَنَّ أَبَا سُفْيَانَ بْنَ حَرْبٍ أَخْبَرَهُ أَنَّ هِرَقْلَ أَرْسَلَ إِلَيْهِ فِي رَكْبٍ مِنْ قُرَيْشٍ كَانُوا تِجَارًا بِالشَّأْمِ فِي الْمُدَّةِ الَّتِي مَادَّ فِيهَا رَسُولُ اللَّهِ ﷺ أَبَا سُفْيَانَ فِي كُفَّارِ قُرَيْشٍ.
