Will my fast be accepted even though I had a wet dream before Fajr and ate suhur, and did not perform ghusl until after sunrise, knowing that I did not pray Fajr until after performing ghusl?

It is permissible to fast for one who wakes up in a state of janabah (ritual impurity), whether due to intercourse at night or a nocturnal emission (wet dream) at night or during the day. Fasting is only invalidated by intercourse during the day in Ramadan. However, delaying prayer due to janabah until after sunrise is forbidden, and one must perform the prayer within its prescribed time and repent for delaying it.
