وَذَكَرْتَ أَنَّكَ زَائِرِي فِي الْمُهَاجِرِينَ وَالْأَنْصَارِ، وَقَدِ انْقَطَعَتِ الْهِجْرَةُ يَوْمَ أُسِرَ أَخُوكَ، فَإِنْ كَانَ فِيكَ [فِيهِ] عَجَلٌ فَاسْتَرْفِهْ، فَإِنِّي إِنْ أَزُرْكَ فَذلِكَ جَدِيرٌ أَنْ يَكُونَ اللهُ إِنَّمَا بَعَثَنِي إِلَيْكَ لِلنِّقْمَةِ مِنْكَ! وَإِنْ تَزُرْنِي فَكَمَا قَالَ أَخُو بَنِي أَسَدٍ: مُسْتَقْبِلِينَ رِيَاحَ الصَّيْفِ تَضْرِبُهُمْ * بِحَاصِبٍ بَيْنَ أَغْوَارٍ وَجُلْمُودِ
