Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 2|Chapter 31
وَ سَأَلَ رَجُلٌ اَلصَّادِقَ عَلَيْهِ اَلسَّلاَمُ فَقَالَ: أَخْبِرْنِي عَنْ لَيْلَةِ اَلْقَدْرِ كَانَتْ أَوْ تَكُونُ فِي كُلِّ عَامٍ فَقَالَ «لَوْ رُفِعَتْ لَيْلَةُ اَلْقَدْرِ لَرُفِعَ اَلْقُرْآنُ ».
A man asked Imam Jafar ibn Muhammad Al-Sadiq عليه السلام: "Inform me about Laylatul Qadr; was it [only in the past], or does it occur every year?" Imam عليه السلام replied: "If Laylatul Qadr were removed, the Quran would be removed."
