It is 3 in the morning and everyone in Uttar Pradesh's Mubarakpur, a village famous for its Banarasi sari weavers, is sleeping. One man is awake, though, and so is his 12-year-old son. These two start their work at 1 am and spend two hours waking all Muslim families in the village for their morning Sehri meal and Azaan before the start of their daylong fast in the month of Ramzan.
