When in December 1766, Ahmad Shah Durrani invaded Lahore and Lahina Singh retired towards Kasur, the Muslim citizens of Lahore pleaded before the Shah to confirm Lahina Singh in the governorship of the Punjab. To this end, the Durrani actually invited Lahina Singh, but the latter declined the proposal. He returned to the Shah the fruit he had sent him, saying that such delicacies were meant for royally alone. The Sikhs, he told the messenger, lived on parched gram. Of this he gave a quantity to the messenger to be presented to Ahmad Shah on his behalf. Lahina Singh occupied Lahore as soon as the Shah left for Afghanistan. Lahina Singh retained a permanent body of 3,000 cavalry and 2,000 infantry and in an emergency he could muster a force of 7,000 horse and 4,000 foot. His territory yielded about 15 lakhs of rupees annually.
