Janamsakhis
The Janamsakhis (Punjabi: ਜਨਮਸਾਖੀ, IAST: Janam-sākhī, lit. 'birth stories'), are popular hagiographies of Guru Nanak, the founder of Sikhism. Considered by scholars as semi-legendary biographies, they were based on a Sikh oral tradition of historical fact, homily, and legend, with the first janamsakhi were composed between 50 and 80 years after his death.
