Rules about the Very Old or One with an Illness

5. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “I once asked abu ‘Abd Allah عليه السلام, about a man who suffers from an illness and is not able to stand up and perform Sujud (prostrations). He (the Imam) said, ‘He is required to perform his Salah (prayer) by making gestures with his head, and placing his forehead on the ground is lovelier to me.’”
