Sa'īd b. al-Musayyib reported in mursal form that the Prophet said, “If anyone recites ten times ‘Say, He is God, One’, a palace will be built for him in paradise because of it; if anyone recites twenty times two palaces will be built for him in paradise because of it; and if anyone recites it thirty times three palaces will be built for him in paradise because of it.” ‘Umar b. al-Khattāb said, “I swear by God, messenger of God, that we shall then produce many palaces for ourselves;” to which he replied, “God's abundant grace is even more comprehensive than that.”
Ibn ‘Umar reported God’s messenger as saying, “Can one of you not recite a thousand verses daily?” Then when he was asked who could recite a thousand verses daily he replied, “Can one of you not recite ‘Rivalry has distracted you’?”(Qur’ān, 102)
Al-Hasan reported in mursal form that the Prophet said, “If anyone recites a hundred verses in a night the Qur’ān will not argue against him that night; if anyone recites two hundred verses in a night he will be recorded as having spent a night standing in prayer; and if anyone recites five hundred to a thousand verses in a night, in the morning he will have a reward equivalent to a qintār*. He was asked what a qintar was and replied that it was twelve thousand .
*This is the measure to which many different values have been ascribed.
‘Abdallāh b. ‘Amr told of a man coming to the Prophet and asking him to teach him to recite. On being told to recite three of the sūras with A. L. R (Qur’ān, 10, 11, 12, 14, and 15) he replied, “I am old, my heart has difficulty in remembering, and my tongue is sluggish.” When told that in that case he should recite three with Hā’ Mīm (Qur’ān, 40 to 46) he gave the same reply and then asked God’s messenger to teach him to recite a comprehensive sūra. He taught him to recite “When is shaken” (Qur’ān, 99) up to the end, and the man said, “I swear by Him who has sent you with the truth that I shall never recite more than that.” Then when the man turned away God's messenger said twice, “The little man has come into a state of felicity.”
