Ramadan is sometimes described as a visitor, whose end is described as a very sad departure. For many residents of NYC, the guest also included visiting imaams and leaders from other parts of the world. The taraweeh prayers in 96th street for example, was led as it is every year, by a visiting sheik of Egypt. The friends at the 14th street Medina Mosque, had the services of a visiting sheik-ul-hadith from Bangladesh.
I found this advertisement for the daily program of a luminary of India, Moulana Palanpuri from Deoband. I was not fortunate to meet him, but I am sure that his leaving was met with sadness by his congregation. I also include a link to the website of the mosque community that hosted the sheik.
