Edhi: Pakistan's 'Angel of Mercy'

Available for over a year

Abdul Sattar Edhi built one of the biggest welfare charities in the world. He started with a small pharmacy in Karachi dispensing free medication to the poor in the 1950s. His wife Bilquis Edhi shared his passion for charity and together they built more than 300 health clinics, trained thousands of nurses, took care of tens of thousands of orphans and set up a nationwide ambulance service. Bilquis Edhi tells Rebecca Kesby how she first met Edhi when she was training to be a nurse. (Photo: Abdul Sattar Edhi and his wife and work partner Bilquis Edhi. Credit Getty Images)
