What time does Fajr namaz become Qadha? At sunrise or a few minutes before? June 3, 2018 by Hasan mahdi 749. Just before dawn a column of whiteness rises upwards from the east. It is called the first dawn. When this whiteness spreads, it is called the second dawn, and the Prime time for Subh prayers. The time for Subh prayers is till sunrise. Sayed Abul Qasim Rizvi
