Mukhtasar Bukhari

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) was asked: "Which deed is the best?" He (peace be upon him) replied: "To have faith in Allah and His Messenger (peace be upon him)." Then he was asked: "Which deed is best after that?" He said: "Jihad in the way of Allah." Then he was asked: "Which deed is best after that?" He replied: "A Hajj that is accepted (by Allah)."
