 Iqbal is widely credited for his work in encouraging the political rejuvenation and empowerment of Muslims, and as a poet not only in India and Pakistan, but also in Iran and Muslim nations in the Middle East.In the Indian rebellion of 1857, both Hindu and Muslims fought the forces allied with the British Empire in different parts of British India.The war's spark arose because the British attacked the "Beastly customs of Indians" by forcing colonial Indian soldiers to handle Enfield P-53 gun cartridges greased with lard taken from slaughtered pigs and tallow taken from slaughtered cows.
