Ibn ‘Abbas said that the Prophet (ﷺ) gave three instructions saying “Expel the polytheists from Arabia, reward deputations as I did”. Ibn ‘Abbas said “He either did not mention the third or I have been caused to forget it. Al Humaidi said on the authority of Sufyan that Sulaiman said “I do not know whether Sa’id mentioned the third and I forgot or he himself did not mention it.”

حَدَّثَنَا سَعِيدُ بْنُ مَنْصُورٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ سُلَيْمَانَ الأَحْوَلِ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَوْصَى بِثَلاَثَةٍ فَقَالَ " أَخْرِجُوا الْمُشْرِكِينَ مِنْ جَزِيرَةِ الْعَرَبِ وَأَجِيزُوا الْوَفْدَ بِنَحْوٍ مِمَّا كُنْتُ أُجِيزُهُمْ " . قَالَ ابْنُ عَبَّاسٍ وَسَكَتَ عَنِ الثَّالِثَةِ أَوْ قَالَ فَأُنْسِيتُهَا . وَقَالَ الْحُمَيْدِيُّ عَنْ سُفْيَانَ قَالَ سُلَيْمَانُ لاَ أَدْرِي أَذَكَرَ سَعِيدٌ الثَّالِثَةَ فَنَسِيتُهَا أَوْ سَكَتَ عَنْهَا
