Jabir (RA):
The Prophet (ﷺ) visited a sick man and saw him praying on a cushion, he threw it away and said, "Pray on the ground, if you can, or else pray by gestures and make your prostration lower than your bowing."
[al-Baihaqi reported it and Abu Hatim graded it Sahih (authentic) in Mawquf form (as a saying of a companion, i.e. Jabir)].
