It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Prophet (peace and blessings be upon him) stood (in prayer) for so long that his blessed feet became swollen. It was said to him (peace and blessings be upon him): "Do you do this when your (past and future) slips have been forgiven?" He (peace and blessings be upon him) said: "Should I not then be a grateful servant?"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abd al-Malik bin Abi Sulayman (may Allah have mercy on him) except Yahya bin Zakariyya al-Nakha'i, and Uthman bin Abi Shaybah is alone in narrating it from him."
