“Bhai Soma is now my shah, or creditor,” remarked the Guru. From that day Bhai Soma came to be known as Soma Shah. Later, he became rich through business. His descendants were living until recent years in the district of Sahival, Dera Isma`il Khan and Bannu, in West Punjab and North-West Frontier Province. The epithet `Shah` is suffixed to their names up to this day.
