The Messenger of Allah (blessings of Allah be upon him and his family) has said: “One who listens to the Qur’an (while it is being recited) will be kept away from the evils of this world; and one who recites the Qur’an will be kept away from the trials of the hereafter. And the person who listens to even one verse of the book of Allah - this is better (for him) than possessing a mansion of gold.”
قالَ رَسُولُ اللّهِ (صَلَّى اللّهُ عَلَيْهِ وَ آلِهِ وَسَلَّمَ): يُدْفَعُ عَنْ مُسْتَمِعِ الْقُرآنِ شَرُّ الدُّنْيا وَ يُدْفَعُ عَنْ قارِيءَ الْقُرآنِ بَلْوى الأَخِرَةِ وَ الْمُسْتَمِعَ آيَةً مِنْ كِتابِ اللّهِ خَيْر مِنْ ثَـبِيرِ ذَهَباً.
