Rules about the Very Old or One with an Illness

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Qasim ibn Muhammad from Ali ibn abu Hamzah from abu Basir who has said the following: “I once said to abu Ja’far عليه السلام, that we speak and say that whoever performs Salah (prayer) in a sitting position without good reason, his two Rak’at are counted as one Rak’at and his two Sajdah (prostration) are counted as one Sajdah (prostration). He (the Imam) said, ‘It is not that way. It is complete for you.’”
