The Reward of the Night Prayer
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 65
وَ رَوَى عَنْهُ اَلْفُضَيْلُ بْنُ يَسَارٍ أَنَّهُ قَالَ: «إِنَّ اَلْبُيُوتَ اَلَّتِي يُصَلَّى فِيهَا بِاللَّيْلِ بِتِلاَوَةِ اَلْقُرْآنِ تُضِيءُ لِأَهْلِ اَلسَّمَاءِ كَمَا تُضِيءُ نُجُومُ اَلسَّمَاءِ لِأَهْلِ اَلْأَرْضِ.
Al-Fudayl ibn Yasar reported from him (Abu Abdullah عليه السلام) who said: "Indeed, the houses in which the Qur'an is recited during the night and where prayer is performed shine for the inhabitants of the heavens just as the stars of the sky shine for the inhabitants of the earth."
