Musnad Ahmad 677:2

Husayn ibn Muhammad narrated to us, Shayban narrated to us, from Mansur, from Ubayd Allah ibn Ali ibn Arfatah al-Sulami, from Khidash Abu Salamah, from the Prophet, peace and blessings of Allah be upon him, that he said: "I enjoin a man regarding his mother, I enjoin a man regarding his mother, I enjoin a man regarding his mother. I enjoin a man regarding his father, I enjoin a man regarding his father, I enjoin a man regarding his father. I enjoin a man regarding his master who is closest to him, even if there is harm upon him in that which annoys him."
