وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ ثَوْرِ بْنِ زَيْدٍ الدِّيلِيِّ، عَنْ عِكْرِمَةَ، مَوْلَى ابْنِ عَبَّاسٍ قَالَ لاَ أَظُنُّهُ إِلاَّ عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، أَنَّهُ قَالَ الَّذِي يُصِيبُ أَهْلَهُ قَبْلَ أَنْ يُفِيضَ يَعْتَمِرُ وَيُهْدِي ‏.‏

Yahya related to me from Malik from Thawr ibn Zayd ad-Dili thatlkrama, the mawla of Ibn Abbas, said, (and Thawr believed it to befrom Abdullah ibn Abbas), "Someone who has intercourse with his wifebefore he has done the tawaf al-ifada should do an umra and sacrificean animal."
