Nothing prevented me from being present at! he Battle of Badr except this incident. I came out with my father Husail (to participate in the Battle), but we were caught by the disbelievers of Quraish. They said: (Do) you intend to go to Muhammad? We said: We do not intend to go to him, but we wish to go (back) to Medina. So they took from us a covenant in the name of God that we would turn back to Medina and would not fight on the side of Muhammad ﷺ. So, we came to the Messenger of Allah ﷺ and related the incident to him. He said: Both, of you proceed (to Medina) ; we will fulfil the covenant made with them and seek God's help against them. (Using translation from Muslim 1787)  

أَنْ أَشْهَدَ بَدْرًا إِلَّا أَنِّي خَرَجْتُ أَنَا وَأَبِي حُسِيلٍ فَأَخَذَنَا كُفَّارُ قُرَيْشٍ فَقَالُوا إِنَّكُمْتُرِيدُونَ مُحَمَّدًا؟ قُلْنَا مَا نُرِيدُهُ مَا نُرِيدُ إِلَّا الْمَدِينَةَ فَأَخَذُوا مِنَّا عَهْدَ اللهِ وَمِيثَاقَهُ لَنَنْصَرِفَنَّ إِلَى الْمَدِينَةِ وَلَا نُقَاتِلُ مَعَهُ فَأَتَيْنَا رَسُولَ اللهِ ﷺ فَأَخْبَرْنَاهُ الْخَبَرَ فَقَالَ انْصَرِفَا نَفِي لَهُمْ بِعَهْدِهِمْ وَنَسْتَعِينُ اللهَ عَلَيْهِمْ  

[Machine] We witnessed Badr, except that my father and I wanted to meet the Messenger of Allah ﷺ , so the polytheists of Quraysh attacked us and said, "You want Muhammad!" We replied, "We don't want him, we only want to go to Medina." They made us swear by Allah and make a covenant that we would go back to Medina and not fight with Muhammad ﷺ . When we passed by them, we went to the Messenger of Allah ﷺ and told him what they had said and what we had said. What is your opinion? He said, "We seek Allah's help against them and nullify their covenant." Then we headed towards Medina. That is what prevented us from witnessing the Battle of Badr.  

أَنْ نَشْهَدَ بَدْرًا إِلَّا أَنِّي وَأَبِي أَقْبَلْنَا نُرِيدُ رَسُولَ اللَّهِ ﷺ فَأَخَذَتْنَا كُفَّارُ قُرَيْشٍ فَقَالُوا إِنَّكُمْ تُرِيدُونَ مُحَمَّدًا فَقُلْنَا مَا نُرِيدُهُ إِنَّمَا نُرِيدُ الْمَدِينَةَ فَأَخَذُوا عَلَيْنَا عَهْدَ اللَّهِ وَمِيثَاقَهُ لَتَصِيرُونَ إِلَى الْمَدِينَةِ وَلَا تُقَاتِلُوا مَعَ مُحَمَّدٍ ﷺ فَلَمَّا جَاوَزْنَاهُمْ أَتَيْنَا رَسُولَ اللَّهِ ﷺ فَذَكَرْنَا لَهُ مَا قَالُوا وَمَا قُلْنَا لَهُمْ فَمَا تَرَى؟ فَقَالَ «نَسْتَعِينُ اللَّهَ عَلَيْهِمْ وَنَفِي بِعَهْدِهِمْ» فَانْطَلَقْنَا إِلَى الْمَدِينَةِ فَذَاكَ الَّذِي مَنَعَنَا أَنْ نَشْهَدَ بَدْرًا  

[Machine] "So, we captured the disbelievers of Quraysh, and they said, 'You want Muhammad!' We replied, 'We do not want him, we only want the city.' So, they made a covenant with us in the name of Allah to let us go to the city and not fight with him. We went to the Prophet ﷺ and informed him of the news. He said, 'Go, fulfill their covenant, and seek Allah's help against them.'"  

فَأَخَذَنَا كُفَّارُ قُرَيْشٍ فَقَالُوا إِنَّكُمْ تُرِيدُونَ مُحَمَّدًا فَقُلْنَا مَا نُرِيدُهُ مَا نُرِيدُ إِلَّا الْمَدِينَةَ فَأَخَذُوا عَلَيْنَا عَهْدَ اللهِ وَمِيثَاقَهُ لَنَنْصَرِفَنَّ إِلَى الْمَدِينَةِ وَلَا نُقَاتِلُ مَعَهُ فَأَتَيْنَا النَّبِيَّ ﷺ فَأَخْبَرْنَاهُ الْخَبَرَ فَقَالَ انْصَرِفَا نَفِي لَهُمْ بِعَهْدِهِمْ وَنَسْتَعِينُ بِاللهِ عَلَيْهِمْ  

"عَنْ حُذَيْفَةَ قَالَ: مَا مَنَعنِى أَنْ أَشْهَدَ بَدْرًا إِلَّا أَنِّى خَرْجتُ أنا وأَبى حِل، فأَخَذَنَا كُفَّارُ قُرَيشٍ، فَقالوا، إنَّكُم تُريدُون مُحَمَّدًا. فقلنا: ما نريده، ما نُريدُ إلا المدينةَ، فَأَخَذُوا مِنَّا عَهْدَ الله ومِيثَاقَهُ لنَنْصَرِفَنَّ إلى المدينةِ ولا نُقَاتِلُ مَعَهُ، فأتَيْنَا رَسُولَ الله ﷺ فأخْبَرَنَاهُ الخَبَرَ. فَقَالَ: انصَرِفَا، فَفِيَا لَهُمْ بِعَهْدهِمْ، ونَسْتَعِينُ الله عَلَيهِمْ".
