Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) was asked: "Which deed is better or most virtuous?" The Prophet (peace be upon him) replied: "To have faith in Allah and His Messenger." He was asked: "Then which deed is most virtuous?" He said: "Jihad in the way of Allah." Then he was asked: "Which deed is most virtuous?" He replied: "An accepted Hajj."
