Hadith no. 1389 (below) is a repeat. Read it here.
Narrated Abu Huraira (radiallaahu `anhu):
In the year prior to the last Hajj of the Prophet when Allahs Apostle (sallallaahu `alayhi wasallam) made Abu Bakr (radiallaahu `anhu) the leader of the pilgrims, the latter (Abu Bakr (radiallaahu `anhu)) sent me in the company of a group of people to make a public announcement: ‘No pagan is allowed to perform Hajj after this year, and no naked person is allowed to perform Tawaf of the Kaba.’
We asked Ibn Umar (radiallaahu `anhu): “May a man have sexual relations with his wife during the Umra before performing Tawaf between Safa and Marwa?” He said, “Allah’s Apostle (sallallaahu `alayhi wasallam) arrived (in Mecca) and circumambulated the Kaba seven times, then offered two Rakat behind Maqam Ibrahim (the station of Abraham), then performed Tawaf between Safa and Marwa.” Ibn Umar (radiallaahu `anhu) added, “Verily! In Allah’s Apostle (sallallaahu `alayhi wasallam) you have a good example.” And I asked Jabir bin Abdullah (radiallaahu `anhu) (the same question), and he replied, “You should not go near your wives (have sexual relations) till you have finished Tawaf between Safa and Marwa. “
Note: “Tawaaf between Safa and Marwa” = Sa`ee.
It is permissible for a man to have intercourse with his wife at any time, except when one of them is in ihraam for Hajj or ‘Umrah, or is fasting, so it is not allowed during the day when one of them is fasting, but it is allowed at night; it is also haraam when the woman is menstruating or bleeding following childbirth.
Allaah says (interpretation of the meaning):
“The Hajj (pilgrimage) is (in) the well-known (lunar year) months (i.e. the 10th month, the 11th month and the first ten days of the 12th month of the Islamic calendar, i.e. two months and ten days). So whosoever intends to perform Hajj therein (by assuming Ihraam), then he should not have sexual relations (with his wife), nor commit sin, nor dispute unjustly during the Hajj”
