Chapter on Fasting with Authorization
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 2|Chapter 31
وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: كَيْفَ تَكُونُ لَيْلَةُ اَلْقَدْرِ خَيْراً «مِنْ أَلْفِ شَهْرٍ» قَالَ «اَلْعَمَلُ اَلصَّالِحُ فِيهَا خَيْرٌ مِنَ اَلْعَمَلِ فِي أَلْفِ شَهْرٍ لَيْسَ فِيهَا لَيْلَةُ اَلْقَدْرِ ».
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام was asked, "How is Laylatul Qadr better than a thousand months?" Imam عليه السلام replied: "Righteous deeds performed on it are better than deeds performed in a thousand months that do not contain Laylatul Qadr."
