Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 2|Chapter 36
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «اَلْوِصَالُ اَلَّذِي نُهِيَ عَنْهُ هُوَ أَنْ يَجْعَلَ اَلرَّجُلُ عَشَاءَهُ سَحُورَهُ ».
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "The continuous fasting (wisal) that is prohibited is when a person makes his evening meal (iftar) the same as his pre-dawn meal (suhoor)."
