that the Messenger of Allah ﷺ said: "Take the Qur'an from four: From Ibn Mas'ud, Ubayy bin Ka'b, Mu'adh bin Jabal, and Salim the freed slave of Abu Hudhaifah." (Using translation from Tirmidhī 3810)
قَالَ رَسُولُ اللهِ ﷺ خُذُوا الْقُرْآنَ مِنْ أَرْبَعَةٍ مِنَ ابْنِ أُمِّ عَبْدٍ فَبَدَأَ بِهِ وَمِنْ مُعَاذِ بْنِ جَبَلٍ وَأُبَيِّ بْنِ كَعْبٍ وَسَالِمٍ مَوْلَى أَبِي حُذَيْفَةَ
