[Machine] One night before dawn, someone said to Abu Ghālib, "Won't you get up and pray, even if you only recite a third of the Qur'an?" I said, "O Abu ʿAbd al-Raḥmān, dawn is approaching, so how can I recite a third of the Qur'an?" He said, "Verily, Surah Al-Ikhlāṣ (Say, He is Allah, the One) [Surah Al-Ikhlāṣ 1] is equivalent to a third of the Qur'an."
لِي ذَاتَ لَيْلَةٍ قَبْلَ الصُّبْحِ يَا أَبَا غَالِبٍ أَلَا تَقُومُ تُصَلِّي وَلَوْ تَقْرَأُ بِثُلُثِ الْقُرْآنِ؟ فَقُلْتُ يَا أَبَا عَبْدِ الرَّحْمَنِ قَدْ دَنَا الصُّبْحُ فَكَيْفَ أَقْرَأُ بِثُلُثِ الْقُرْآنِ؟ قَالَ إِنَّ سُورَةَ الْإِخْلَاصِ {قُلْ هُوَ اللَّهُ أَحَدٌ} [الإخلاص 1] تَعْدِلُ ثُلُثَ الْقُرْآنِ
