The white iron grill gate encloses the actual tomb of the Saint. People visit the shrine and make a wish by tying the thread to the grill. Once their wish is met, they come back and remove their thread and offer a chaddar (cloth sheet) to the tomb along with incense and flowers.
You must cover your head before entering into the main courtyard. You can buy what's called a Namaz cap from one of the many stalls that are located inside. They only cost about Rs10. Ladies will have to cover arms and legs.
Inside the second gate are two huge Degs (cauldrons). Rice sugar, ghee (butter) and dried fruits are cooked for distribution to the public as tabarruk. However, if you look inside, they have money lying on top of sand as a donation to the upkeep of the Dargah.
Qawwali is an integral part of the rituals here. A qawwali is a song in the praise of Allah. They are sung by the qawwals (devotional singers). It is believed that Amir Khusraw (1253-1325 A.D.), a famous Sufi saint and an expert, both in Indian and Persian music, introduced Qawwali into South Asian music. Qawwali as a musical form is closely linked to the sufic traditions of Islam and the particular practices that Sufi scholars developed to achieve closeness to God.
A custom, like with Hinduism, is to buy flowers as offerings. There are loads of stalls within the Dargah complex that offer these lovely decorated flowers for devotees.
