Abu Hurairah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) was asked: "Which deed is the best, or which deed is the most excellent?" He replied: "To have faith in Allah and His Messenger." It was asked: "Then which?" He said: "Jihad, it is the hump of righteousness." It was asked: "O Messenger of Allah! Then which?" He said: "An accepted (Mabroor) Hajj." Imam Tirmidhi says:
