Al-Adab Al-Mufrad
Book 53, Hadith 13
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ: حَدَّثَنَا عَبْدُ اللهِ بْنُ دُكَيْنٍ، سَمِعَ كَثِيرَ بْنَ عُبَيْدٍ قَالَ: كَانَتْ عَائِشَةُ رَضِيَ اللَّهُ عَنْهَا إِذَا وُلِدَ فِيهِمْ مَوْلُودٌ، يَعْنِي: فِي أَهْلِهَا، لاَ تَسْأَلُ: غُلاَمًا وَلاَ جَارِيَةً، تَقُولُ: خُلِقَ سَوِيًّا؟ فَإِذَا قِيلَ: نَعَمْ، قَالَتِ: الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ.

Musa ibn Isma‘il related to us: ‘Abd Allah ibn Dukayn related to us: I heard Kathir ibn ‘Ubayd say: Whenever a child was born among ‘A’ishah’s family—meaning her household—she would not ask whether it was a boy or a girl. She would ask: ‘Was the child created sound and whole?’ If they answered, ‘Yes,’ she would say: ‘Praise be to Allah, Lord of the worlds.’
Notes and open questions — unreviewed
The source explicitly says that ‘A’ishah did not ask whether the newborn was a boy or a girl; the pronoun in her question is left gender-neutral in English.
سويًّا here conveys soundness or being whole/formed properly.
