[Machine] Al-Qa'nabi reported that Muhammad ibn Abdullah ibn Muslim ibn Akhi Al-Zuhri narrated from his uncle, Ibn Shihab, who narrated from Humaid ibn Abdul Rahman ibn Auf, who narrated from his mother, Umm Kulthum bint Uqbah ibn Abi Muayt. She reported that the Messenger of Allah ﷺ was asked about the verse "Say, He is Allah, the One." He replied, "It is equivalent to one-third of the Quran, or it is like the whole Quran."
