It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) stood and made a supplication the like of which the people had never heard, and sought refuge in a way the like of which the people had never heard. So some people said to him (peace and blessings be upon him): "O Messenger of Allah! How can we supplicate the way you supplicated and seek refuge the way you sought refuge?" He (peace and blessings be upon him) said: "Say: 'Allahumma inna nas'aluka mimma sa'alaka Muhammadun 'abduka wa rasuluk, wa nasta'idhu mimma ista'adha minhu Muhammadun 'abduka wa rasuluk' (O Allah, we ask You for the good that Your servant and Messenger Muhammad (peace and blessings be upon him) asked You for, and we seek refuge in You from that from which Your servant and Messenger Muhammad (peace and blessings be upon him) sought refuge)."
No one narrated this hadith from Ata bin Yasar except Muhammad bin al-Munkadir, and from Ibn al-Munkadir only Muhammad bin Abd al-Rahman bin Mujabbar, while Yazid bin Harun is alone in narrating it.
