It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him): "Whenever the Prophet (peace and blessings be upon him) saw a person whose physical form was altered (i.e. afflicted with a disability or disease), he would prostrate; when he saw a monkey, he would prostrate; and when he woke from his sleep, he would prostrate to Allah."
No one narrated this hadith from Muhammad bin al-Munkadir (may Allah have mercy on him) except his son Yusuf (may Allah have mercy on him), and Abd al-Rahman bin Ubaydullah (may Allah have mercy on him) is alone in narrating it from him.
