Hawzah News Agency – Eight things are disapproved for a junub:

1- eating and drinking; however, if one washes his face and hands and rinses his mouth, then eating and drinking are not disapproved; and if one only washes his hands, then the disapproval is lessened;

2- reciting more than seven verses of the Qur’an that do not contain an obligatory sajdah;

3- touching the cover, margins, or spaces between the writing of the Qur’an with any part of the body;

4- keeping the Qur’an with oneself;

6- dyeing hair with henna or something similar;

7- rubbing oil on the body;

8- having sexual intercourse after having a wet dream, i.e. after semen has been ejaculated in one’s sleep.
