New Fatwas I have heard of mosques having two separate sermons in one mosque at different times. I understand the need for that with parking and overcrowding. The confusion is that the first one will be before the sun passes the zenith (before Thuhr). Q: I noticed an Imam leading two congregations of Jumua prayer and have heard that the scholars teach that the follower must have the same intention of the Imam for the prayer to be valid. I have noticed a difference between the calculations for the time for Fajr. One calculation is almost 20 minutes more than the other. How can I be sure which one to use?
