Is it allowed to eat before taking a Ghusl? (When Ghusl is compulsory say after a wet dream) and if it is allowed to eat Seher (breakfast before the start of a fast) before taking a Ghusl?
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
The scholars agreed in a consensus that it is not a condition for a person not to be in a state of sexual defilement when eating and there is no difference between him/her eating the pre-down meal or other foods.
Allah knows best.
