The Reward of the Night Prayer
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 65
وَقَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: «إِنَّ اَللَّهَ تَبَارَكَ وتَعَالَى يُحِبُّ اَلْمُدَاعِبَ فِي اَلْجَمَاعَةِ بِلاَ رَفَثٍ اَلْمُتَوَحِّدَ بِالْفِكْرِ اَلْمُتَخَلِّيَ بِالْعِبَرِ اَلسَّاهِرَ بِالصَّلاَةِ.
Imam Muhammad ibn Ali Al-Baqir عليه السلام said: "Indeed, Allah سبحانه وتعالى, Blessed and Exalted, loves one who engages in light-heartedness in a gathering without indecency, one who reflects deeply while alone, one who contemplates lessons from life in solitude, and one who stays awake for prayer."
