Hadith 8:2176
Abu Bakr narrated to us, he said: Jarir narrated to us, from Mughira, from Ibrahim, who said: If a person in the state of ihram for an 'umrah has intercourse with his wife while she is in the state of ihram for an 'umrah, he said: He must offer a sacrificial animal for each one of them, and they shall proceed to complete their 'umrah.
حدثنا أبو بكر قال حدثنا جرير عن مغيرة عن إبراهيم قال إذا واقع المحرم بعمرة إمراته وهي محرمة بعمرة قال يهدي في كل واحد منهما هديا ويمضيان لعمرتهما
