Heer Ranjha was written by Waris Shah. Some historians say that the story was the original work of Shah, written after he had fallen in love with a girl named Bhag Bhari.[2] Others say that Heer and Ranjha were real personalities who lived under the Lodi dynasty in India of the 15th and 16th century and that Waris Shah later utilised these personalities for his novel that he wrote in 1766. Waris Shah states that the story has a deeper meaning, referring to the unrelenting quest that man has towards God.

Waris Shah was born in Jandiala Sher Khan, Punjab, present-day Pakistan into a reputed Sayyid family and was a descendant of Sayyid Muhammad Al-Makki through his son Sayyid Badruddin.[2] His father's name was Gulsher Shah and mother's name was Kamal Banu. Waris's parents are said to have died when he was young. Waris spent years in search of the perfect spiritual guide. Waris Shah acknowledged himself to be a disciple of an ustad from Kasur, namely Hafiz Ghulam Murtaza from whom he received his education. After completing his education, Waris moved to Malka Hans, a village twelve kilometres north of Pakpattan. Here he resided in a small room, adjacent to a historic mosque now called Masjid Waris Shah, until his death.[1] Other poets later added their own verses in Qissa Waris Shah throughout the history. It is estimated that there are 11069 forged [3] verses in the commonly available Qissa Waris Shah. One of the oldest and most accurate copy of Qissa Waris Shah published by Kripa Ram [4] in 1916 is available in the Punjab Public Library in Lahore.

Many verses of Waris Shah are widely used in Punjab in a moral context, for instance:

Examples:

Naa adataan jaandiyan ne, Bhavein katiye poriyan poriyan ji (A man never abandons his habits, even if he is hacked to pieces)

Waris rann, faqir, talwar, ghora; Chare thok eh kisse de yar nahin (Waris says that woman, beggar, sword and horse, these four are never anyone's friends)
Waris Shah faqir di aqal kithe; eh pattian ishq padhiyan hun (It is beyond the wisdom of faqeer Waris Shah (to write this verse), (But) these lessons are taught by Love)
Eh rooh qalboot da zikr sara nal aqal de mel bulaya ee (This entire reference is about Soul meeting with the Divine, Beloved which has been contrived with great wisdom)

Ajj Akan Waris shah nu(today we are calling Dead Warris shah )
