that the Messenger of Allah ﷺ said: "Would one of you like to recite a third of the Qur'an during a night? Whoever recited: Allaahu Al-Wahid As-Samad then he has recited a third of the Qur'an."
قَالَ رَسُولُ اللَّهِ ﷺ أَيَعْجَزُ أَحَدُكُمْ أَنْ يَقْرَأَ فِي لَيْلَةٍ ثُلُثَ الْقُرْآنِ مَنْ قَرَأَ اللَّهُ الْوَاحِدُ الصَّمَدُ فَقَدْ قَرَأَ ثُلُثَ الْقُرْآنِ وَفِي الْبَابِ عَنْ أَبِي الدَّرْدَاءِ وَأَبِي سَعِيدٍ وَقَتَادَةَ بْنِ النُّعْمَانِ وَأَبِي هُرَيْرَةَ وَأَنَسٍ وَابْنِ عُمَرَ وَأَبِي مَسْعُودٍ
