Those who consider prostrating on a pillow by a sick person to be disliked

Hazrat Ata narrates that Hazrat Ibn Umar (may Allah be pleased with them) visited Hazrat Safwan during his illness and saw that he was prostrating on a pillow. Hazrat Ibn Umar (may Allah be pleased with them) forbade him from doing so and said that he should only gesture.

Muhammad says that prostrating on a pillow is an innovation (bid'ah).

Hazrat Abu Harb bin Abi Al-Aswad says that Abu Al-Aswad was afflicted with paralysis, and he used to prostrate on a cushion which we would raise towards him. Regarding this, we asked Hazrat Ibn Umar (may Allah be pleased with them) and he said that if a person has the ability to prostrate on the ground, then that is fine; otherwise, he should suffice with just indicating (the prostration).
