Hadith 8:1684
Abu Bakr narrated to us, he said: Ibn ‘Ulayyah narrated to us, from Yunus, from al-Hasan, who said: If one combines Hajj and ‘Umrah, then there is one circumambulation (tawaf) and one effort (sa’i). And if one performs Qiran (combining them in a specific manner), then there are two circumambulations and two efforts.
حدثنا أبو بكر قال حدثنا بن علية عن يونس عن الحسن قال إذا جمع بين الحج والعمرة فطواف واحد وسعي واحد وإن أقرن فطوافان وسعيان
