Musannaf Ibn Abi Shaybah 34400 — Reports on Abdullah bin Masud

Abu al-Malih al-Hudhali (may Allah have mercy on him) said: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) used to screen him when he (peace and blessings be upon him) bathed, and used to wake the Prophet (peace and blessings be upon him) when he (peace and blessings be upon him) slept, and used to walk with him (peace and blessings be upon him) alone in the land.
