suhur

If a person was forced for some reason to have suhur late at night, and kept eating while the Fajr Adhan is taking place, does he have to stop eating immediately upon hearing the call or can he continue eating until the end of the call?

hello i am planning to fast this year but i do not intend to get up in the mornings for fajr, i wanted to ask if i skip eating fajr will my fast still be accepted or is fajr essential? thank you

Please advise us with regard to suhur. Is it conditional for the fast to be correct or not?
