Ibn ‘Abbās and Anas b. Mālik reported Allah's Messenger ﷺ as saying that “When is shaken” (Qur’ān, 99) is equivalent to half the Qur’ān, “Say, He is Allah, One” (Qur’ān, 112) is equivalent to a third of the Qur’ān, and “Say, O infidels” (Qur’ān, 109) is equivalent to a quarter of the Qur’ān. Tirmidhī transmitted it.
