The Edhi Foundation, founded by Edhi, runs the world's largest volunteer ambulance Service (operating 1,500 of them) and offers 24-hour emergency services. It also operates free nursing homes, orphanages, clinics, women's shelters, and rehab centres for drug addicts and mentally ill individuals. It has run relief operations in Africa, Middle East, the Caucasus region, eastern Europe, and the United States where it provided aid following Hurricane Katrina in 2005. His son Faisal Edhi, wife Bilquis Edhi, and daughters managed the daily operations of the organization during his ill health. He is often referred to as Pakistan's version of Mother Teresa, and the BBC wrote that he was considered "Pakistan's most respected figure and was seen by some as almost a saint."
