Narrated Al-Bara' bin 'Azib (ra):On the day of Hudaibiya, the Prophet (ﷺ), the Prophet (ﷺ) made a peace treaty with the Al-Mushrikun on three conditions:1. The Prophet (ﷺ) would return to them any person from Al-Mushrikun (polytheists, idolaters, pagans).2. Al-Mushrikun pagans would not return any of the Muslims going to them, and3. The Prophet (ﷺ) and his companions would come to Makkah the following year and would stay there for three days and would enter with their weapons in cases, e.g., swords, arrows, bows, etc.Abu Jandal came hopping, his legs being chained, but the Prophet (ﷺ) returned him to Al-Mushrikun.
وَقَالَ مُوسَى بْنُ مَسْعُودٍ حَدَّثَنَا سُفْيَانُ بْنُ سَعِيدٍ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ ـ رضى الله عنهما ـ قَالَ صَالَحَ النَّبِيُّ صلى الله عليه وسلم الْمُشْرِكِينَ يَوْمَ الْحُدَيْبِيَةِ عَلَى ثَلاَثَةِ أَشْيَاءَ عَلَى أَنَّ مَنْ أَتَاهُ مِنَ الْمُشْرِكِينَ رَدَّهُ إِلَيْهِمْ، وَمَنْ أَتَاهُمْ مِنَ الْمُسْلِمِينَ لَمْ يَرُدُّوهُ، وَعَلَى أَنْ يَدْخُلَهَا مِنْ قَابِلٍ وَيُقِيمَ بِهَا ثَلاَثَةَ أَيَّامٍ، وَلاَ يَدْخُلَهَا إِلاَّ بِجُلُبَّانِ السِّلاَحِ السَّيْفِ وَالْقَوْسِ وَنَحْوِهِ. فَجَاءَ أَبُو جَنْدَلٍ يَحْجُلُ فِي قُيُودِهِ فَرَدَّهُ إِلَيْهِمْ. قَالَ لَمْ يَذْكُرْ مُؤَمَّلٌ عَنْ سُفْيَانَ أَبَا جَنْدَلٍ وَقَالَ إِلاَّ بِجُلُبِّ السِّلاَحِ.
