Husayn says: Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) got down from his she-camel and began driving it along, chanting rajaz verses and saying: And they walk with us, treading softly; if the bird's omen proves true, we shall have intercourse. He mentioned intercourse and did not use an allusion, so I said: O Ibn Abbas! You speak of rafath while you are in the state of ihram? He said: Rafath is that by which one turns to women.
