Prayer of the Sick, the Unconscious, the Weak and the Infirm, the Elderly and Others

Murazim ibn Hakim al-Azdi said: "I was ill for four months and did not perform any voluntary prayers (nawafil) during that time. I mentioned this to Imam Jafar ibn Muhammad Al-Sadiq عليه السلام, Imam عليه السلام said: 'There is no obligation upon you for making up those prayers. Indeed, the sick person is not like the healthy one. Whatever Allah سبحانه وتعالى has made overpowering upon him, Allah سبحانه وتعالى is more entitled to excuse him.'"
