[Machine] His grandfather, Sa'id ibn Zaid, asked the Messenger of Allah ﷺ about his father, Zaid. He said, "O Messenger of Allah, my father, Zaid ibn 'Amr ibn Nufayl, was as you have seen him and as he reached you. If he had lived to see you, he would have believed in you. So, ask forgiveness for him." The Messenger of Allah said, "Yes, I will ask forgiveness for him." He then asked forgiveness for him and said, "Verily, he will come on the Day of Resurrection as a single nation." It is mentioned that he was seeking the truth and he died while in his quest. Al-Dhahabi remained silent about him in his summary.  

أَنَّ جَدَّهُ سَعِيدَ بْنَ زَيْدٍ سَأَلَ رَسُولَ اللَّهِ ﷺ عَنْ أَبِيهِ زَيْدٍ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ أَبِي زَيْدَ بْنَ عَمْرِو بْنِ نُفَيْلٍ كَانَ كَمَا رَأَيْتَ وَكَمَا بَلَغَكَ وَلَوْ أَدْرَكَكَ لَآمَنَ بِكَ فَاسْتَغْفِرْ لَهُ قَالَ «نَعَمْ» فَاسْتَغْفَرَ لَهُ وَقَالَ «فَإِنَّهُ يَجِيءُ يَوْمَ الْقِيَامَةِ أُمَّةً وَاحِدَةً» فَكَانَ فِيمَا ذَكَرُوا يَطْلُبُ الدِّينَ وَمَاتَ وَهُوَ فِي طَلَبِهِ سكت عنه الذهبي في التلخيص
