It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "The Messenger of Allah (peace and blessings be upon him) used to pray (voluntary) prayer until his blessed feet were about to crack; then after that his blessed body became heavy, so he (peace and blessings be upon him) began to pray sitting; and when he (peace and blessings be upon him) intended to finish the surah, he would stand up and complete it, then bow."
No one narrated this hadith from Abdullah bin Yazid bin Hurmuz except Rishdin, and Zuhayr bin Abbad is alone in narrating it from him.
