It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once someone asked the Holy Prophet (peace and blessings be upon him), "Which deed is the most virtuous?" The Holy Prophet (peace and blessings be upon him) replied, "To have faith in Allah and His Messenger." The questioner asked, "Then which deed is most virtuous?" He replied, "Jihad in the way of Allah." The questioner asked, "After that?" He replied, "A Hajj that is accepted (by Allah)."
