Shah Kalim Allah Jahanabadi (there are many variations on the spelling and format of his name) was a great Sufi Saint in the Chishti lineage. He founded the Kaleemi branch of the order that migrated to Hyderabad, India. Eventually this led to Hazrat Inayat Khan meeting Syed Muhammad Abu Hashem Madani in Hyderabad. Madani then sent Inayat Khan to the west.
His Dargah is located near the Jammah Masjid, opposite the Red Fort, in Delhi, India.
The saint was the man who took on himself the task of bringing about a moral reawakening during the last days of the reign of Aurangzeb. The saint was born in Delhi around 1650 and his father, Sheikh Noorullah, was a well-known astronomer, calligraphist and professor of theology and he studied theology under the guidance of Sheikh Bunharuddin and Sheikh Bahlool, two famous ulemas of the time. After completing his studies, he renounced the world and became a sufi. At the place where the shrine is situated once stood Khanam-ka-bazaar which housed khanqa— a religious abode-cum-inn which was later converted into a college.
There are several stories about the miracles performed by the saint including one in which he commanded the Yamuna River to behave itself when the river flooded half of Delhi and he was also supposed to cure disease including the blindness of a girl. Every year, a two-day urs is held at the shrine which is attended by those who are on their way back from the pilgrimage to Ajmer Sharif.
His book “Kashkul Kalimi” is a collection of Azkar (plural of zikr) from various Chishti saints. It has been translated into English and is part of the recently published “Sufi Meditation and Contemplation” translated and edited by Siraj al Haqq Scott Kugle, available at the Omega Publications web site.
