No Sex

Pilgrimage takes place in appointed months. Whoever undertakes it must avoid sexual intercourse, wrongdoing, and disputes. Whatever good you do, Allah knows it. Take provisions, but the best provision is righteousness.

2:197The pilgrimage is (in) the well-known months, and whoever is minded to perform the pilgrimage therein (let him remember that) there is (to be) no lewdness nor abuse nor angry conversation on the pilgrimage. And whatsoever good ye do Allah knoweth it. So make provision for yourselves (Hereafter); for the best provision is to ward off evil. Therefore keep your duty unto Me, O men of understanding.
