[Machine] It was revealed to the Messenger of Allah ﷺ that a nation would be raised for five years. It is reported that the Messenger of Allah ﷺ said, "Sa'id ibn Zaid ibn 'Amr will embrace Islam before the Messenger of Allah ﷺ enters the house of Al-Arqam and before he calls people to Islam." Sa'id ibn Zaid witnessed the battles of Uhud, Al-Khandaq (the Trench), and all the other scenes with the Messenger of Allah ﷺ , but he did not witness the Battle of Badr.  

أَنْ يُوحَى إِلَى رَسُولِ اللَّهِ ﷺ بِخَمْسِ سِنِينَ فَرُوِيَ عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ يُبْعَثُ أُمَّةً وَاحِدَةً وَأَسْلَمَ سَعِيدُ بْنُ زَيْدِ بْنِ عَمْرٍو قَبْلَ أَنْ يَدْخُلَ رَسُولُ اللَّهِ ﷺ دَارَ الْأَرْقَمِ وَقَبْلَ أَنْ يَدْعُوَ فِيهَا النَّاسَ إِلَى الْإِسْلَامِ وَشَهِدَ سَعِيدُ بْنُ زَيْدٍ أُحُدًا وَالْخَنْدَقَ وَالْمَشَاهِدَ كُلَّهَا مَعَ رَسُولِ اللَّهِ ﷺ وَلَمْ يَشْهَدْ بَدْرًا
