أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُبَارَكِ، عَنْ عُمَرَ بْنِ عَبْدِ الْوَاحِدِ، عَنْ الْأَوْزَاعِيِّ، قَالَ: سَأَلْت الزُّهْرِيَّ عَنْ الرَّجُلِ يَبْتَاعُ الْجَارِيَةَ لَا تَبْلُغْ الْمَحِيضَ وَلَا تَحْمِلُ مِثْلُهَا، كَمْ يَسْتَبْرِئُهَا ؟، قَالَ: "ثَلَاثَةَ أَشْهُرٍ".
It is narrated from Imam Awza'i, may Allah have mercy on him, that I asked Imam Zuhri, may Allah have mercy on him, if a man buys a minor slave girl who has neither menstruated nor is capable of becoming pregnant like those of her age, what will be the duration of her 'istibra' (waiting period)? He replied: Three months.
