The Messenger of Allah (prayers of Allah be upon him and his family) has said: “These hearts rust just as iron rusts; and indeed they are polished through the recitation of the Qur’an.” Irshadul Qulub; Page 78 Hadith Number 7 قالَ الإِمامُ جَعْفَرُ بْنُ مُحَمَّدٍ الصّادِقُ (عَلَيْهِ السَّلامُ): أَلْقُرآنُ عَهْدُ اللّهِ إِلـى خَلْقِهِ فَقَدْ يَـنْـبَغِي لِلْمَرْءِ الْمُسْلِمِ أَنْ يَنْظُرَ فِي عَهْدِهِ وَ إِنْ يَقْرَأُ مِنَ الْقُرآنِ فِي كُلِّ يَوْمٍ خَمْسِينَ آيَةٍ.

Imam Ja’far ibne Muhammad as-Sadiq (peace be upon him) has said: “The Qur’an is the trust of Allah (given) to His creations, therefore it is desirable for every Muslim to look at this trust and to recite (a minimum of) 50 ayat (verses) of the Qur’an everyday.” Usulul Kafi, Volume 2, Page 609 Hadith Number 8 قالَ أَمِيرُ الْمُؤْمِنِينَ عَلِيُّ ابْنُ أَبِي طالِبٍ (عَلَيْهِ السَّلامُ): أَلْـبَيْتُ الَّذِي يُقْرَأُ فِيهِ الْقُرآنَ وَ يُذْكَرُ اللّهُ عَزَّوَّجَلَّ فِيهِ تَكْـثُرُ بَرَكَتَهُ وَ تَحْضُرُهُ الْمَلائِكَةُ وَ تَهْجُرُهُ الشَّياطِينَ وَ يُضِيءُ لأَهْلِ السَّمآءِ كَما تُضِيءُ الْكَواكِبَ لأَهْلِ الأَرْضِ.

In addition, that house will shimmer for the people of the sky, just like the stars shimmer for the people on the Earth.” Usulul Kafi, Volume 2, Page 610 Hadith Number 9 قالَ رَسُولُ اللّهِ (صَلَّى اللّهُ عَلَيْهِ وَ آلِهِ وَسَلَّمَ): فِي وَصاياهُ لِعَلِيٍّ (عَلَيْهِ السَّلامُ): يـا عَلِيُّ عَلَيْكَ بِتِلاوَةِ الْقُرآنِ فِي كُلِّ حالٍ. In his last testament to ‘Ali (peace be upon him), the Messenger of Allah (blessings of Allah be upon him and his family) told him: “O’ ‘Ali!

I advice you to recite the Qur’an in every state (which you may find yourself in).” Man La Yahdhuruhul Faqih, Volume 4, Page 188 Hadith Number 10 قالَ رَسُولُ اللّهِ (صَلَّى اللّهُ عَلَيْهِ وَ آلِهِ وَسَلَّمَ): لَيْسَ شَيْء أَشَدُّ عَلى الشَّيْطانِ مِنَ الْقِراءَةِ فِي الْمُصْحَفِ نَظَراً.
