Musannaf Ibn Abi Shaybah 31304 — What is mentioned of the supplication

Sayyidah Aishah (may Allah be pleased with her) said that when the Messenger of Allah (peace and blessings be upon him) was near death, and he (peace and blessings be upon him) had with him a cup containing water, he (peace and blessings be upon him) put his hand into the cup and wiped his face with the water, then began to supplicate: "O Allah, help me through the agonies of death."
