ʿAbdullah (bin Masʿud) was mentioned before ʿAbdullah bin ʿAmr. The latter said, "That is a man I continue to love because I heard Messenger of Allah ﷺ saying, ' Learn the recitation of the Qur'an from (any of these) four persons: ʿAbdullah bin Masud, Salim the freed slave of Abu Hudhaifa, Ubai bin Kaʿb, and Muʿadh bin Jabal." I do not remember whether he mentioned Ubai first or Muʿadh.  

ذَاكَ رَجُلٌ لاَ أَزَالُ أُحِبُّهُ بَعْدَ مَا سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ اسْتَقْرِئُوا الْقُرْآنَ مِنْ أَرْبَعَةٍ مِنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ فَبَدَأَ بِهِ وَسَالِمٍ مَوْلَى أَبِي حُذَيْفَةَ وَأُبَىِّ بْنِ كَعْبٍ وَمُعَاذِ بْنِ جَبَلٍ قَالَ لاَ أَدْرِي بَدَأَ بِأُبَىٍّ أَوْ بِمُعَاذٍ
