Arabic (Original)
حَدَّثَنَا وَكِيعٌ عَنْ سُفْيَانَ عَنْ أَبِي قَيْسٍ عَنْ عَمْرِو بْنِ مَيْمُونٍ عَنْ أَبِي مَسْعُودٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قُلْ هُوَ اللَّهُ أَحَدٌ تَعْدِلُ ثُلُثَ الْقُرْآنِ.
English Translation
Waki' narrated to us from Sufyan, from Abu Qays, from Amr ibn Maymun, from Abu Mas'ud, who said: The Messenger of Allah, peace and blessings be upon him, said: 'Say, He is Allah, the One' is equivalent to a third of the Qur'an.
