I am from Malaysia and studying in UK. I was not aware of the difference bt fajar and asar time between the shafie and hanafi mazhab. A large portion of last ramadhan i ate to the last minute before sehri ends using the hanafi time. Do I have to perform qada’? JazakAllah Khair for your attention.
There is no difference of opinion in the terminating time of Sehri and
commencing time for Fajr Salaat.
All the scholars are unanimous that Sehri ends upon the commencing of
Subh-e-Saadiq (break of dawn) when the horizontal light in the sky appears.
Fajr time commences at Subh-e-Saadiq. Your fasts were valid and you do not
have to make Qadhaa of your fasts.
and Allah Ta’ala Knows Best
