What is the latest time we can do ghusal after sehri? Is it permissible to do ghusal in the morning after sunrise in Ramadan?
You should do ghusl at least before Fajr salaah because it is a farz salaah. The worst case may be 15 mins before sunrise whereby you should read fajr before sunrise. But during fasting, care should be taken that no water goes in the throat. Else fasting is valid and correct even if ghusl is done after sehri time.
