NIDHAN SINGH, a Varaich Jatt of Patti in present day Amritsar district of the Punjab, was, according to Sarup Singh Kaushish, Guru kian Sakhian, the husband of the celebrated Sikh heroine, Mai Bhago. He was one of the warriors who fell fighting in the battle of Muktsar fought on 29 December 1705 and who were blessed by Guru Gobind Singh as mukte, the Liberated Ones. NIDHAN SINGH (d. 1850) or Nidhan Singh Hathu, i.e. Nidhan Singh the Inflexible, son of Jassa Singh, was a bold warrior in Sikh times who, inheriting Daska in Sialkot district from his father, had acquired considerable territory.
SAHOVAL, village 8 km southwest of Sialkot (32"30`N, 74"32`E) in Pakistan, is sacred to Guru Nanak (1469-1539) who once came here travelling from Sialkot and , according to local tradition, stayed under a ber tree (Ziziphus maiiritiana) near a pond for seven days. A gurdwara was later raised here and the pond lined into a sarovar or holy tank named Nanaksar. Gurdwara Nanaksar preserved within its compound the ber tree, reverently called Ber Sahib, under which Guru Nanak is said to have halted temporarily. The shrine was abandoned at the time of the 1947 exodus following the partition of the Punjab.
