The pandemonium, which
injured 60 more people, started after the gates were closed to the
residence of Syedna Mohammed Burhanuddin, who had died the day before at
age 102, CNN sister network CNN-IBN reported.
Burhanuddin was the head of a denomination of Islam known as Dawoodi Bohra.
His funeral will continue as scheduled, CNN-IBN reported.
India has seen deadly stampedes at religious events before.
In October at least 115 died, when Hindu pilgrims crossing a bridge to a temple broke into a panic, as a rumor spread that the bridge was about to give way.
About 25,000 people were on the bridge at the time, and many jumped off it into the Sindh River.
In February, at least 36 died at a stampede at a train station, as millions of people clamored to get to the Ganges River for a Hindu religious festival.
