Ibn `Abbas (May Allah be pleased with them) reported: The Messenger ofAllah (sallallaahu ’alayhi wasallam) said, "He who does not memorize any part from the Qur'an he is like the ruined house.''
[At-Tirmidhi].
Commentary: This Hadith means that the heart of that Muslim is devoid of grace of spiritualism and Grace of Allah who does not remember by heart any portion of the Qur'an, in the same way as a deserted house is deprived of inhabitants and Blessings of Allah. What welearn from this is that every Muslim must remember some portion ofthe Qur'an so that he is safe from the admonition mentioned in this Hadith.
