He was unconscious for three days – does he have to make up his prayers?

He was given a sedative in the hospital so that he would not feel pain, and he remained unconscious for three days. When he regains consciousness, should he make up his prayers?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy on him) was asked this question, and replied:

If it is three days or less, then he should make up his prayers – by analogy with one who sleeps. If it is more than that then he does not have to make up his prayers – by analogy with one who is insane. And Allaah knows best.
