Arabic hadith text
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، لَمْ يَكُنْ يَسْأَلُهُ أَحَدٌ مِنْ أَهْلِهِ عَقِيقَةً إِلاَّ أَعْطَاهُ إِيَّاهَا وَكَانَ يَعُقُّ عَنْ وَلَدِهِ بِشَاةٍ شَاةٍ عَنِ الذُّكُورِ وَالإِنَاثِ ‏.‏
Translation

Yahya related to me from Malik from Nafi that if any of Abdullahibn Umar's family asked him for an aqiqa, he would give it to them. Hegave a sheep as aqiqa for both his male and female children.
