A number of our people have narrated from Sahl ibn Ziyad from certain persons of Ahwaz who has said the following: “Al-Rida’ (a.s.), has said, ‘In the body there is a vein called ‘Isha’.

If one does not take dinner, it continues praying against him until morning; and it says, ‘May Allah make you hungry just as you kept me hungry, and may Allah make you thirsty just as you kept me thirsty.’ No one of you must neglect taking dinner, even if it is one morsel of bread or a sip of water.’” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (22/102))
