Hadith 1773
وحَدَّثَنَاه حَسَنٌ الْحُلْوَانِيُّ ، وَعَبْدُ بْنُ حُمَيْدٍ، قَالَا : حَدَّثَنَا يَعْقُوبُ وَهُوَ ابْنُ إِبْرَاهِيمَ بْنِ سَعْدٍ ، حَدَّثَنَا أَبِي ، عَنْ صَالِحٍ ، عَنْ ابْنِ شِهَابٍ بِهَذَا الْإِسْنَادِ وَزَادَ فِي الْحَدِيثِ ، وَكَانَ قَيْصَرُ لَمَّا كَشَفَ اللَّهُ عَنْهُ جُنُودَ فَارِسَ مَشَى مِنْ حِمْصَ إِلَى إِيلِيَاءَ شُكْرًا لِمَا أَبْلَاهُ اللَّهُ ، وَقَالَ فِي الْحَدِيثِ مِنْ مُحَمَّدٍ عَبْدِ اللَّهِ وَرَسُولِهِ ، وَقَالَ : إِثْمَ الْيَرِيسِيِّينَ ، وَقَالَ : بِدَاعِيَةِ الْإِسْلَامِ .
This hadith has been narrated on the authority of Ibn Shihab with the same chain of transmitters but with the addition: "When Allah inflicted defeat on the armies of Persia, Caesar moved from Hims to Aelia (Bait al-Maqdis) for thanking Allah as He granted him victory." In this hadith these words occur: "From Muhammad, servant of Allah and His Messenger," and said: "The sin of your followers," and also said the words: "to the call of Islam".
