According to another version, he (ﷺ) said to his Companions, "Is anyone of you incapable of reciting one-third of the Qur'an in one night?" They considered it burdensome and said: "O Messenger of Allah, which of us can afford to do that?" He (ﷺ) said, "Surat Al-Ikhlas [Say: He is Allah (the) One] is equivalent to one-third of the Qur'an."
[Al- Bukhari].
وفي رواية: أن رسول الله صلى الله عليه وسلم قال لأصحابه:" أيعجز أحدكم أن يقرأ بثلث القرآن في ليلة" فشق ذلك عليهم، وقالوا: أينا يطيق ذلك يارسول الله: فقال :" {قل هو الله أحد} ثلث القرآن.". (( رواه البخاري)).
