Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 66
وَ رَوَى زَكَرِيَّا اَلنَّقَّاضُ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: فِي قَوْلِ اَللَّهِ عَزَّ وَ جَلَّ «لاٰ تَقْرَبُوا اَلصَّلاٰةَ وَ أَنْتُمْ سُكٰارىٰ حَتّٰى تَعْلَمُوا مٰا تَقُولُونَ» قَالَ «مِنْهُ سُكْرُ اَلنَّوْمِ.
Zakariyya al-Naqqad reported from Imam Muhammad ibn Ali Al-Baqir عليه السلام regarding the words of Allah سبحانه وتعالى, the Mighty and Majestic: "Do not approach prayer while you are intoxicated until you know what you are saying" (Surah An-Nisa 4:43). Imam عليه السلام said: "This includes the intoxication of sleep."
