Safwan, from al-Ala, from Muhammad ibn Muslim, from Abu Ja’far عليه السلام, peace be upon him, who said:
I (narrator) asked Imam عليه السلام about ‘a man who becomes unconscious and then regains consciousness.’ Imam عليه السلام said: “He makes up what he missed, and he gives the call to prayer for the first one and gives the iqamah for the rest.”
