Shirazi has a post on Hasan Abdal near Islamabad where “The legend has it that in 1521 AD, while passing through then deserted area on a very hot day, Guru Nanak's companion Bhai Mardana got very thirsty. The Guru suggested that he go to the Saint Baba Wali Qandhari who lived in a hut atop a nearby hill and ask for water.”
