وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَعْرِبُوا الْقُرْآنَ وَاتَّبِعُوا غَرَائِبَهُ وَغَرَائِبُهُ فَرَائِضُهُ وَحُدُودُهُ» . رَوَاهُ الْبَيْهَقِيّ فِي شعب الْإِيمَان

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.” Dārimī transmitted it.
