Jabir (RA):
The saying of the Prophet (ﷺ) to a sick person who prayed on a cushion: The Prophet (ﷺ) threw it away and said, "Pray on the ground, if you are able to do so; otherwise, pray by gesturing signs and make your prostration lower than your bowing."
[al-Baihaqi reported it through a strong chain of narrators, but Abu Hatim regarded it as Mauquf (saying of a Companion)].
