عَنْ أَسْمَاءَ بِنْتِ يَزِيدَ رَضِيَ اللَّهُ عَنْهَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ الْعَقِيقَةُ حَقٌّ عَنِ الْغُلَامِ شَاتَانِ مُكَافَأَتَانِ وَعَنِ الْجَارِيَةِ شَاةٌ
It is narrated from Sayyida Asma bint Yazid (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him) said: Aqeeqah is a right; for a boy, two similar goats and for a girl, one goat will be sacrificed.
