Mishkat al-Masabih 2060

Ibn Abbas and Anas ibn Malik reported God’s messenger as saying that “When is shaken” (Qur’an, 99) is equivalent to half the Qur’an, “Say, He is God, One” (Qur’an, 112) is equivalent to a third of the Qur’an, and “Say, O infidels” (Qur’an, 109) is equivalent to a quarter of the Qur’an. Tirmidhi transmitted it.
