From him, from Abdullah ibn Muhammad who said: I wrote to him; “May I be ransomed for you, it has been narrated from Abu Abdillah عليه السلام, peace be upon him, regarding a sick person who becomes unconscious for several days. Some have said he makes up the prayer of the day in which he regains consciousness, and some have said he makes up the prayers of three days and leaves what is beyond that, and some have said that there is no make-up upon him.” So Imam عليه السلام wrote: “He makes up the prayer of the day in which he regains consciousness.”
