Mishkat al-Masabih 30 Fine Qualities كتاب المناقب 244

عَنِ ابْنِ مَسْعُودٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: ” اقْتَدُوا بِاللَّذَيْنِ مِنْ بَعْدِي مِنْ أَصْحَابِي: أَبِي بَكْرٍ وَعُمَرَ وَاهْتَدُوا بِهَدْيِ عمّارٍ وَتَمَسَّكُوا بِعَهْدِ ابْنِ أُمِّ عَبْدٍ ” . رَوَاهُ التِّرْمِذِيُّ

Ibn Mas’ud reported the Prophet as saying, “When I am gone copy those two of my companions, Abu Bakr and `Umar, follow the guidance of `Ammar, and hold fast to the injunction of Ibn Umm `Abd.” Hudhaifa’s version has “Believe what Ibn Mas’ud tells you” Instead of “Hold fast to the injunction of Ibn Umm `Abd.” Tirmidhi transmitted it.
