From Sahih Bukhari (Hadith 1794):
Narrated `Amr bin Dinar:We asked Ibn `Umar whether a man who had performed the Tawaf of the Ka`ba but had not performed the Tawaf between As-Safa and Al-Marwa yet, was permitted to have sexual relation with his wife. He replied, "The Prophet (ﷺ) arrived (at Mecca) and circumambulated the Ka`ba seven times and then offered a two rak`at prayer behind Maqam-Ibrahim and then performed the going (Tawaf) between As-Safa and Al-Marwa (seven times) (and verily, in Allah's Messenger (ﷺ) you have a good example." And we asked Jabir bin `Abdullah (the same question) and he replied, "He should not go near her till he has finished the going (Tawaf) between As-Safa and Al-Marwa
