Chapter: The Prayer of the Sick
If a sick person is unable to stand, he prays seated, performing the bowing and the prostration. Should he be incapable of bowing and prostrating, he gestures with his head, making the prostration lower than the bowing, and he must not raise any object to his face to prostrate upon.

If he cannot sit, he lies on his back with his feet toward the qiblah and gestures for both bowing and prostration. Should he lie on his side with his face toward the qiblah and gesture, that is acceptable. If he is unable even to gesture with his head, he postpones the prayer; he is not to gesture with his eyes, his mind, or his eyebrows.

If he can stand but cannot bow and prostrate, standing is no longer required of him; he may pray seated, indicating the movements with gestures instead. If a healthy person begins part of his prayer standing and then falls ill, he completes it seated, bowing and prostrating; if he cannot bow and prostrate, he gestures, and if he cannot sit, he completes it lying down.

If he has prayed by gesture and later regains the ability to bow and prostrate, he must start the prayer anew.

Whoever loses consciousness and thereby misses five prayers or fewer must make them up once he has recovered. If the unconsciousness causes him to miss more than that, he is not required to make them up.
