Surat al-Ikhlas equals a third of the Qur'an

سورة الإخلاص تعدل ثلث القرآن

The Prophet told his Companions that he would recite a third of the Qur'an to them, then recited Surat al-Ikhlas and said that it equals a third of the Qur'an, in Muslim Sahih Muslim 1888 — a deed that equals a greater one and in the Muwatta Muwatta 557. The text is an equation, not a number: it sets a short act equal to a long one and names no good deeds to add up, so the calculator shows it as a written result.
