Making up the Night Prayer
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 76
قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «كُلُّ مَا فَاتَكَ بِاللَّيْلِ فَاقْضِهِ بِالنَّهَارِ قَالَ اَللَّهُ تَبَارَكَ وَ تَعَالَى: «وَ هُوَ اَلَّذِي جَعَلَ اَللَّيْلَ وَ اَلنَّهٰارَ خِلْفَةً لِمَنْ أَرٰادَ أَنْ يَذَّكَّرَ أَوْ أَرٰادَ شُكُوراً » »
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "Whatever you miss during the night, make it up during the day, as Allah سبحانه وتعالى the Exalted said: 'And it is He who made the night and the day in succession for whoever desires to remember or desires gratitude.'”.
