This is a double story! This GurGaddi story is both how Guru Gobind Singh bestowed the Guruship to the Khalsa Panth and later to the Siri Guru Granth.
After Guru Gobind Singh's time, during the time of Maharaja Ranjit Singh, there was a purely devoted fearless Khalsa named Akali Phula Singh. After taking a hukam from the Guru he wouldn't delay his battle plan to attack at dawn. He was the only one to charge in to battle against the Afghan army at first. He fought bravely without fear of death. He said, "The Khalsa of Guru Gobind Singh can do anything."
