Mishkat al-Masabih, 2139

Mu'ādh al-Juhani reported God’s messenger as saying, “If anyone recites the Qur’ān and acts according to its contents, on the day of resurrection his parents will be given to wear a crown whose light is better than the light of the sun in the dwellings of this world if it were among you. So what do you think of him who acts according to this?” Ahmad and Abū Dāwūd transmitted it.

وَعَن معَاذ الْجُهَنِيّ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ قَرَأَ الْقُرْآنَ وَعَمِلَ بِمَا فِيهِ أُلْبِسَ وَالِدَاهُ تَاجًا يَوْمَ الْقِيَامَةِ ضَوْءُهُ أَحْسَنُ مِنْ ضَوْءِ الشَّمْسِ فِي بُيُوتِ الدُّنْيَا لَوْ كَانَتْ فِيكُمْ فَمَا ظَنُّكُمْ بِالَّذِي عَمِلَ بِهَذَا؟» . رَوَاهُ أَحْمد وَأَبُو دَاوُد
