Peer Buddhu Shah (13 June 1647 – 21 March 1704), was a Muslim divine whose real name was Badr ud Din, who was an admirer and ally of Guru Gobind Singh. He visited the Guru regularly and at one point introduced 500 shias Muslims Pathan soldiers who had been expelled by Aurangzeb to the Guru who employed them. However, when these soldiers faced battle against the Hill chiefs, they deserted the Guru’s army.
The Peer was very upset by this action and brought many hundreds of his own followers and his family members to assist the Guru’s force. The Guru was most impressed by this dedication shown by the Peer in this urgently needed support. However, in supporting the Guru, this action made him an enemy of the Mughals, who in 1704 executed him.
When Banda Singh Bahadur came to know that the Peer had been executed because he helped Guru Gobind Singh in the battle of Bhangani, he avenged the Pir’s death by storming Sadhaura and killing Usman Khan, who had been responsible of the Peer’s death. Pir Buddhu Shah’s descendants migrated to Pakistan in 1947. Their ancestral house in Sadhaura has since been converted into a Gurdwara named after Pir Buddhu Shah.
