Musannaf Ibn Abi Shaybah 20500 — What is mentioned on the virtue

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) was asked: "Which deed is better or best?" The Prophet (peace and blessings be upon him) said: "Believing in Allah and His Messenger." He was asked: "Then which deed is best?" He said: "Striving (jihad) in the way of Allah." He was asked again: "Which deed is best?" He said: "An accepted Hajj."
