Abu Dawud Book 1, Hadith Number 342.

Chapter : A person who is sexually defiled is permitted to eat anything before washing.

Narated By Hafsah, Ummul Mu’minin : The Prophet (PBUH) said: It is necessary for every adult (person) to go for (saying) Friday (prayer), and for everyone who goes for Friday (prayer) washing is necessary.

Abu Dawud said: If one takes a bath after sunrise, even though he washes because of seminal emission, that would be enough for him for his washing on Friday.
